Last update on

If you’re wondering if Google PageSpeed Insights score matters, our short answer is: yes. Google PageSpeed Insights grade is important (and reliable).

It hasn’t always been like that for us. In the past, we said that you shouldn’t care about the Google PageSpeed Insights score because the grade alone wasn’t an indicator of speed.

While there could still be a difference between the Google PageSpeed score and your site’s loading time, things have changed — and we need to keep up with the news.

Starting from June 2021, the Google PageSpeed score will be closely related to your SEO performance because of the Core Web Vitals included in the new Page Experience ranking factor.

In this article, you’ll learn why Google PageSpeed Insights is important and accurate to measure different aspects of your site’s user experience, including performance.

You’ll also understand why you should always pay attention to the loading time — Google PageSpeed Insights could still be a bit misleading, and at WP Rocket, we care a lot about this metric!

Lastly, you’ll get some tips to improve your mobile PageSpeed score, the most important grade.

You’ll get answers to all your most popular questions and doubts on the PageSpeed Insights importance, including the evergreen question: does the 100/100 page speed score matter?

What Google PageSpeed Insights is And What the PageSpeed Score Means

Let’s refresh the basics.

Google PageSpeed Insights is one of Google’s tools to measure and improve your site’s performance on mobile and desktop devices.

As the first thing, PageSpeed Insights provides you with the overall page’s performance score.

The Google PageSpeed score is determined by Lighthouse, an open-source tool powered by Google’s team. Lighthouse runs different audits, including a performance one. After running the performance audit and assessing several metrics, Lighthouse will determine the Performance score — that is the same score that Google PageSpeed provides.  

The Google PageSpeed score is based on lab data. It means that Google PageSpeed Insights, through Lighthouse, collects performance data in a controlled environment. The simulation is done with the predefined device and network settings.

Being based on predefined conditions — for instance, the Internet connection — the Google PageSpeed score doesn’t reflect real user experience at 100%.

That’s why the PageSpeed Insights tool also provides Field data. Real field-data is based on the aggregated data that Google Chrome collects from users and makes available in the Chrome User Experience Report (CrUX).

This data is highly valuable because it captures real user experience — it’s also why this data can slightly differ from the lab data and isn’t always available.

Field Data stored in the CrUX contains all three Core Web Vitals. You can quickly identify them by the blue flag: Largest Contentful Paint (loading performance), First Input Delay (interactivity), Cumulative Layout Shift (visual stability).

At this point, it’s useful for you to know that the Lab data contains only the Largest Contentful Paint and Cumulative Layout Shift scores. The First Input Delay metric can’t be measured without real user interaction. That’s why the performance score considers the Total Blocking Time metric, used as a proxy.

Last but not least, field data is valuable because it’s how Google evaluates the SEO ranking — more on this topic just in the next section!

Why Google PageSpeed Is Important (and Why It Affects SEO)

Google PageSpeed matters because it can affect SEO from two different perspectives: mobile speed and user experience.

Both mobile performance and user experience are related to specific ranking factors:

  1. In July 2018, Google rolled out the Speed Update, and mobile page speed became a direct ranking factor, both for Google Search and Ads.
  2. In June 2021, the Page Experience signal will roll out as an SEO ranking factor. This new ranking factor measures the user experience of a page. It includes several signals: mobile-friendliness, HTTPS-security, intrusive interstitial guidelines, safe-browsing, and the already mentioned Core Web Vitals metrics.

On the one hand, mobile page speed has been a ranking factor for more than two years. Hopefully, you’re already taking care of your site’s mobile performance. If you’re still in doubt, we’ve got you covered in the last section of this article with some performance optimization tips.

On the other hand, the three Core Web Vitals focus on how users interact with your page and account for 70% of the overall PageSpeed score weight. Meaning, they’re quite relevant in determining the PageSpeed Insights score.

Even though the Google PageSpeed score as a whole is not a ranking factor, you need to take care of the Core Web Vitals metrics. As we said, they’re part of the new Page Experience ranking signal and will affect your organic visibility.

You can find below the score required for each Core Web Vital. You should start thinking about how to enhance them! (Hint: WP Rocket is the easiest way to improve your Core Web Vitals in a few clicks).

Is Google PageSpeed Insights Reliable & Accurate?

Yes, Google PageSpeed Insights is now pretty reliable and accurate when measuring the full user experience on your site. Thanks to the different metrics included, it gives you an accurate overview of how users interact with your site.

The tool became more and more reliable thanks to the latest changes.

In November 2018, Google released PageSpeed 5.0. The new version started to use the Chrome User Experience Report dataset (CrUX) mentioned above. It also started to use Lighthouse audits.

Then, in May 2020, Lighthouse 6.0 arrived. New metrics have been added — the same ones that you now see in the PageSpeed Insights tool and capture the overall performance and user experience.

That’s why you can rely on the PageSpeed score and its metrics to understand how your site performs. And, of course, you should follow the PageSpeed Insights recommendations to improve your score.

Since the Google PageSpeed score is now more accurate, an improvement in the grade would usually reflect an improvement in the loading time.

Wait… does it mean that the PageSpeed score doesn’t reflect how fast a website is? The honest answer is: it depends.

Why the Google PageSpeed Score Isn’t Equal to the Loading Page Performance

At WP Rocket, we care about educating users on web performance and giving them the best tools to understand how to approach this complex topic.

That’s why we want to point out that the Google PageSpeed score could not reflect how fast your website is.

To be clear: you can have a good PageSpeed score, but your site could not be as fast. Or you can have a fast website and a bad PageSpeed score.

We’ll share a couple of examples — you might relate to them!

  • Following the PageSpeed Insights recommendations won’t always make your site faster.

    Let’s take the popular recommendation of removing render-blocking JavaScript. If you solve this issue, your PageSpeed score will improve. However, if you measure your loading time with Pingdom, you won’t necessarily notice an improvement.
  • The more your PageSpeed score is low, the more the loading time will improve — but don’t expect proportional enhancements.If your Google PageSpeed score jumps from 10 to 90, it’s quite likely that your loading time will improve — let’s say, it will decrease from 2s to 1.5s.
    If your Google score jumps from 80 to 90, your loading time will only decrease slightly — for instance, from 2s to 1.9s.

It’s because the Google PageSpeed score reflects an overall user experience more than the loading time.

The loading time is just the page loading time. On the other hand, the Google PageSpeed score takes into account six metrics that go beyond that.

In the next section, we’ll share practical examples to explain how the Google PageSpeed score is calculated. You’ll see how the metrics play together for both performance and user experience.

For now, keep in mind that you have to take care of both loading time and Google PageSpeed score. They both matter for different reasons:

  • If your loading time is high, you’re likely to lose users and conversions.
  • If your PageSpeed score is not good, likely, the Core Web Vitals metrics won’t be good as well. And your site will be penalized from an SEO perspective. Don’t forget: Core Web Vital accounts for 55% of the PageSpeed score.

How Google PageSpeed Insights Score Is Calculated

We’ve seen how the Google PageSpeed score is relevant for SEO performance. Let’s now take a closer look at the metrics that can make a difference in your grade.

As we said, the speed score that you see on the top of your PageSpeed report is based on the lab data analyzed by Lighthouse.

What’s a Good Google Pagespeed Score?

If you’re wondering what Google PageSpeed grade you should aim for, you should know that a good score starts from 90 — the threshold giving you the green color.

The score is divided into three buckets:

  • Good: your score is 90 or above (green)
  • Needs improvements: your score is 50 to 90 (orange)
  • Poor: your score is below 50 (red).

PageSpeed Insights Metrics and Weights

The Google page speed score includes six metrics:

It’s essential to know that each metric has a different weight.

There are metrics that are more important than others for determining your overall score. Improving some of them will have a more significant impact on the score than others.

Here you can see how the weight is calculated:

Speaking of Core Web Vitals, you can see that the Largest Contentful Paint and the Total Blocking Time are the metrics that make the biggest difference. They both account for 55% of the overall score.

If you have a terrible Largest Contentful Paint or Total Blocking Time, it’s also likely that your loading time will be quite high. It’s because these two metrics relate to the loading performance and the interactivity of the page.

Take a look at how bad the performance score gets if you increase your Largest Contentful Paint or Total Blocking Time performance:

How the performance score changes according to LCP and TTB

By improving both metrics, your loading time will also decrease. How much it will decrease depends on your initial score —  as we explained in the examples above.

In June 2021, Lighthouse 8.0 increased the weighting of the Cumulative Layout Shift metric, which now accounts for 15%

You now understand what metrics matter the most for your SEO and performance optimization. It’s time to get some good results and quickly improve both Core Web Vitals and loading time in one-go!

Google PageSpeed Insights Mobile vs. Desktop: What’s the Difference?

The only difference between Google PageSpeed Insights mobile vs. desktop is the score you can get. Getting a good PageSpeed mobile score is more complicated than achieving the same score on a desktop.

It’s because the connection on mobile is slower. Simple as that.

By default, Lighthouse simulates a 3G connection. Comparing the mobile score to the desktop-grade is unfair. The desktop connection will always be faster.

There are also other reasons why your mobile score tends to be lower than the desktop one. Let’s go over them and see how you can improve your performance from mobile.

How to Improve a Low Mobile PageSpeed Score

Do you have a low-performance score from mobile? Image optimization could probably be the key to solve your issues.

You’ll solve a bad mobile performance following two overlooked best practices: resizing and serving correct images for mobile devices and optimizing images’ sizes (not just dimensions!).

Here are a couple of practical examples:

  • Let’s say that you have a slider containing a big and large image — around 2000 pixels. The image would be fine from the desktop, where the average width resolution is 1900 or 1400 pixels. On the other hand, the maximum width on mobile is 700 pixels.
    The image’s dimensions will have a substantial negative impact on mobile. And it will add up to the issue about the 3G connection.

That’s why you should always load the correct size depending on the device and then serve scalable resized images on mobile.

  • The size of image files can also cause lower mobile performance. If you optimize an image from 1 MB to 500 KB, your page will be faster. The lower your page size is, the faster the page will load. It’s especially true when you have a slower connection.That’s why image optimization will always have a more significant impact on your mobile score than on the desktop one. The worse your connection is, the more critical image optimization is.

Does It Matter to Get a 100/100 Google PageSpeed Score on Mobile?

We’ll be as honest as possible. It’s almost impossible to get a 100 score mobile for the reasons explained above. It’s easier to get such a score on a desktop.

The truth is, there is no difference between the 95 and 100 — both for mobile and desktop. As for the Web Core Vitals performance, your goal should be to get a green score. And the green score starts from 90 — it will be enough.

Don’t stress out! Google is not going to penalize you because you have a 97 score instead of 100. The user experience will be the same — and it’s everything that matters. But… if you still want to score 100% on Google’s Page Speed test, check out our case study and learn the best speed tips!

What About PageSpeed Insights vs. Other Performance & Speed Test Tools?

Let’s take a look at two of the main performance and speed tools. You’ll have another proof the Google PageSpeed Insights is a reliable tool and that loading time is a slightly different metric.

GT Metrix vs. Google PageSpeed Insights

The difference between PageSpeed insight and GTmetrix is the location used for the performance test. They both use the Lighthouse performance metrics now, so the score should be the same.

Still, you might see a discrepancy between the two scores.

That’s because the closer your server is to the location of the server used to perform the test, the highest the score will be.

On the one hand, Google PageSpeed Insights will calculate your score using the nearest server. On the other hand, if you don’t have an account in GTmetrix, you’ll use the default server located in Vancouver.

If possible, you should always run your speed test by choosing your nearest location.

You can see how your performance score can change according to the server location:

The performance score can vary according to the server location

Google PageSpeed Insights vs. Pingdom

You can’t compare Google PageSpeed Insights and Pingdom. Pingdom doesn’t use Lighthouse, and it doesn’t give any information on Core Web Vitals.

It just provides a grade based on the loading time.

Pingdom performance grade

That’s why you should always take a look at Pingdom. It’s a different thing. As we saw, you need both performance and loading time scores to give your users the best experience.

Wrapping Up

Google PageSpeed Insights has evolved quickly. It gained undeniable importance thanks to the Core Web Vitals, which will make a difference in your organic performance very soon.

Google’s tool is reliable, and now you know how to look critically at the performance score and each metric — without forgetting the loading time!

Learning something more about testing web performance helps you understand what the priorities are and what your approach should be. Good luck with the new ranking factor rolling out!

Remember that you can save yourself time and let WP Rocket do the job for you. WP Rocket will automatically apply 80% of web performance best practices. You don’t even have to touch any settings. You’ll see an improvement in speed and your PageSpeed Insights score right away — no technical knowledge required, we promise!

Another Great Post,
I am using Pingdom Tools and GT Metrix for testing my website.

"No site gets a perfect grade, in fact it’s pretty much impossible to achieve, and since it doesn’t correlate to speed, why bother?"

Check out - http://fastwp.de
...then say it again :P

But i agree... pagespeed have a couple of good recommendations, but in the end too much "bullshit" and sometimes the recommendations are not for every project a good choice. Be carefull when you trust all this things from google and catch the score. When you not know what you doing, some of thesere tricks and recommendations slow down your site more and don't came with a speed up.

Thanks, This is good to know! I have spent far to much time chasing the pagespeed grade.

For all our Assessments we use a whole bunch of speed testers, Google Pagespeed is not even one of them :)
Great article, keep 'em coming!

This article is for me :D Thanks lucy ;)
I think the best record of gtmetrix score is belonged to sahifa demo page. 99 for google and 94 for yahoo!

I find this post to be wrong on some points. Now I will admit that Page Speed Insights is not the best tool and some things that they recommend can't be solved its just how things are. However, you are wrong on some several key points.

1. The Optimize CSS delivery. This actually greatly improves the load time of the website and won't cause the "unstyled" content that you mention. You later seem to correct the point but it is going to confuse users.

What the optimize CSS delivery means, is to load the critical css in the header with an inline style. This will load let's say in some cases 10kb of CSS and the rest will be loaded with async in the footer. This greatly reduces the load time as the main css to load the page is there to avoid that "unstyled content" and the rest of the extra styling (some widgets or other less important code) will be loaded afterwards. This is great for mobile devices where the download speed can be really poor,

On mobile devices the user will be able to read the content and interact with the site a little bit before the rest of it loads thus greatly improving the overall load time and the time it takes for the user to have a readable website.

2. ALL JS should be loaded in the footer. This is the standard and it should be pushed for every website. Even JQuery can be added to the footer so it should be a priority to build your site with this in mind. While WordPress Rocket doesn't have a "one click" solution you need to push for it to improve the load time of your website.

Now I agree that things like the save 3 bytes in your JS file is a waste of time. Or compress your image to save 1kb of space is not worth your time.

But the general rule of thumb is anything on your server (caching, headers, etc, etc) or JavaScript and CSS files you should optimize.

Hey Scott,

1. The CSS position doesn't change at all the global loadtime.
This will change a little bit the perception. Could be good indeed to have 2 CSS like Lucy says in the post and what you explain (that's basically the same).
That's impossible to set up automatically in a WordPress website.

Putting everything in the footer is terrible for user experience. Here is a great exemple : http://recordit.co/Rh7uZPsFU1
With a slower connexion that's even worst.

So our recommendation is : it's better to have everything in the header compare to everything in the footer.

And the best recommendation is to have a small CSS file and to load them conditionally.

2. Nope, nope and nope :) But to moderate my words web performance rules can't be general and are different website by website.

Do you know that iOS won't display ANYTHING until it finds the JS files.
So putting JS in the footer will be absolutely terrible for the critical rendering path.
We can see it on your own website : http://www.webpagetest.org/result/150618_WW_D2Q/1/details/
You will see that the start render (the green bar) starts when all the JS are found (not loaded).

Plus regarding to user experience, most of the websites have JS interactions on the top (sliders for exemple), so loading jQuery and all dependencies at the end could be bad. This means that all the interactions are not working and even sometimes not displaying until everything is loaded.

So in my opinion the rule is the same than CSS. jQuery and what we see directly on the header, and the rest on the footer.

Very nice post, thanks for this info

I agree wit the article content but some clients want to see a 100/100 on Goggle page speed insight.

To explain the meaning of a site speed i Wrote this article http://www.azzali.net/il-vostro-sito-e-abbastanza-veloce-per-google/(sorry Italian only) where at the end i put a table with speed results after installing WP rocket cache plugin and obviosly a mention of it.

@Fabrizio
That's your job as a professional to explain to your clients that chasing the 100 is worthless, like we do with that blog post.
I agree, that's very difficult to do.

@Jean

It's true that there is no way to do it automatically in Wordpress but that does not mean it can be ignored. Your main goal is to get the content visible to the reader as quickly as possible. By optimizing the load of CSS you will see a decrease in bounce rate. Which is the main goal of the webmaster, more views and a lower bounce rate.

If that's what Safari mobile does than its breaking the standard and need to rectify the mistake. Safari also occupies an extremely small percentage of the market and does not dictate how your website should be optimized. The standard and recommendation is for all JS to be in the footer and to be loaded with async. Therefore what I said was right Safari is at fault here and needs to fix their browser which is already one of the worst on the market.

It doesn't matter if some websites use a slider on my own websites I use a slider and I can get all of my JS deferred in the footer and its still functional. Again a website built properly can get it to work and be optimized for speed.

That aside its a matter of fact here. Large CSS in the header slows down the rendering and is a pain for mobile users. JS should be in the footer and loaded with async while we inline the critical CSS and load the rest with async.

@scott

Remember this blog post in focused on our market which is WordPress.

"Safari also occupies an extremely small percentage".

Q4 2014: Chrome 37%, IE 14%, Safari iOS 12%, Firefox 11%.
That's not what I call an extremely small percentage.

Regarding JS, the webperformance community is rather agree that JS should be split in header/footer and not only footer.
Plus you can notice that all the biggest websites (FB, Instagram, Airbnb, etc) are doing this (header and footer). I'm pretty confident that these guys have an infinity more experience compare to you or me.
So we can say there are no debate on this point :)

Some statistics say different (more or less for Safari).

That being said most users are not using safari therefore we need to accommodate for the majority of users.

On the JS its decides it goes in the footer. And the only time it should be in the head is if there is a dependency or something that you simply can't solve in which case you still have performance degradation.

It's true that Facebook and other companies are doing it but they are running on top of the tier hardware and have the bandwidth to support faster download speeds. While most of our setups are shared hosting vps or rarely dedicated / multiple dedicated servers. So it truly comes down to their infrastructure at that point in which case even though they are not doing the standard they still load very quickly lol.

I think what your plugin does is perfect. It makes websites fast for those who other wise would have no clue what they are doing lol. Your plugin makes WordPress simple because users don't have to play around with W3 or Super Cache for hours with settings they don't know how to use.

I just think we should put more focus on educating people what the standards are and even if your plugin doesn't offer said feature you compare the amount of time invested vs the overall improvement.

the google speed should be only reference to see where your website is not soo good.. but it is wery tricky sometimes

A great and informative article filled with - "useful time-saving facts"!
Much appreciated! Sharing this one.

TWEET THIS BOX
By the way..... could you please point me in the direction on how to create the nifty "tweet this" box function you have in the article? Loved it.

Keep up the good work,
-Erik

So, overall I like the intent of the article, but you're spreading some wrong information. Google is not perfect and neither are their tools, but if you really want lots more organic traffic from showing up high in Google search results pages, then you need to pay attention to what Google's tools share with you.

I was recently at a SES convention in Miami where the head of Google Product Development was speaking and she shared (regarding mobile optimizing your site) that even if your site is perfect, but not in the eyes of Google, it will not show up appropriately. It has to be "Google Mobile-Friendly". In this case, your sites need to be fast and load properly in the eyes of Google, and the insights that they provide are in most cases the same indicators they use to serve up the best user-experience for visitors.

It is tough to make a website get an "A" in Google Page Speed Insights, but it is possible and worth it. They are creating and using established Best Practices that all web developers should be using. Until some other site can provide you the same amount of traffic or more, then we need to pay attention to the tools they provide.

It’s preferable for performance that JavaScript files are loaded in the footer of your site, or asynchronously so that they don’t block the downloading of other assets on your site, therefore slowing it down.

There are a few other items about JavaScript in the footer in the comments as well.

If you look at how current versions of Chrome behave though, you'll see that just putting JavaScript in the footer doesn't always change things.

You can use this page as an example. The "devicepx-jetpack.js" reference is at the bottom of the page, but it is the 11th resource to be loaded ( http://www.webpagetest.org/result/150624_MG_1A5F/1/details/ ) out of 51. The pre-loader scans the HTML looking for script references, then gives them a higher priority in requesting them.

I've written about this previously https://josephscott.org/archives/2015/04/scripts-at-the-bottom-is-not-enough/

Hello,

This plugin below, ensures PageSpeed 100/100
https://wordpress.org/plugins/speed-booster-pack/

My question is:
 
This plugin is compatible with wp-rocket ?

Regarding Google PageSpeed agree on everything 100%. It makes sense to look to his rekkomedatsiyam but PageSpeed not an indicator of speed. But if the option Rocket lazy loading images, the Pingdom does not have time to upload pictures, so the speed is much faster. Actually option lazy loading of images - this is very good in terms of speed and does not interfere with the reader.

I understand what you are trying to say and agree with most conclusions here, however I have some doubts about using Pingdom's Load Time as the main indicator of site's speed. It's a common agreement that what matter most to users is a perceived performance.

For example check http://www.smashingmagazine.com/ with cleared cache, as a WP site with 99/100 in Google PageSpeed test. It feels like displaying instantaneously due to prioritizing above the fold content and resulting speed index below 1000. And yet the load time in the Pingdom test is above 2 seconds.

http://tools.pingdom.com/fpt/#!/cxWU85/http://www.smashingmagazine.com/
http://www.webpagetest.org/result/150716_Q9_MT3/

Not saying Speed Index should be the only performance indicator, for example additional network activity can slow down browsers especially on mobiles but should be at least mentioned here shortly.

Keep up great job.

@Lubos

I partially agree with your point. It's important to properly measure the load time. Smashing Magazine is using a CDN, to when you are using PingDom it's very important to do multiple tests to be sure that the static content is properly cached by the CDN pop servers.
But yes

For exemple after a few tests, 797ms => http://tools.pingdom.com/fpt/#!/bQNg0e/http://www.smashingmagazine.com/

In the other hand, I fully agree that Smahing Magazine have done great optimization regarding to perception of the load time :)

I am using Wp Rocket after several other plugins and I am surprised for the good control of the source code and the results in term of pure speed.

My question is about this point: "When the Google bot crawls your site, it cannot see your “grade”, only your speed".

Are you totally sure that Google bot doesn't use any check system alike the score parameter using in Google Speed Test?

@Enrico: I think it doesn't make senses for the Google bots to make a Google Speed test for these reasons:
- they have to be fast to crawl a website, a pagespeed test takes is very long
- you can have 100% and a page loading time to 10 seconds, so Google Bot should give you some "points" only for the grade? No, it's why the only metrics that everybody must take care is the page loading time

that's a great tool and very powerful plugin and helpful support
my site: http://alafdal.org/
load speed was 16 s or more
after installing the plugin and activate - huge difference happened
you can check now my speed 654ms

that's the great number ، that's a dream didn't come in my mind

A good advace how we achieved 100 Insight Score for our web site http://www.itransition.com - We set up an additional check for user-uploaded images – some of them were not completely optimized and had unnecessary metadata etc. The module performed lossless-optimization for these images.

You may be right, that Google does not really measure the correct speed, but the way Google measures speed is the way Google used it in its SEO-Relevant rankings. So Google Page speed still is important.

Thanks for these insights! I will send clients here when they complain about their score.

It makes me chuckle when Google suggests that I fix one of their problems:

Minify JavaScript:
Minifying https://www.gstatic.com/…ha/api2/r20150928175454/recaptcha__en.js could save 555B (1% reduction) after compression.

or

Optimize images:
Losslessly compressing https://maps.gstatic.com/…mapfiles/api-3/images/tmapctrl4_hdpi.png could save 1,000B (22% reduction).

you are not right. I got for https://meko.lv/ 100/100 for first page and otpimised most landingapges. This is new website and it is ranking fast . If you get 100 your page will be faster just because less http requests and smaller code.

This article so wrong on the functional analysis of page speed insights. It may be correct in saying it doesn't matter [to the average wordpress blog owner]. But is perfect page speed necessary for the average wordpress blog? No. But for developers working on "real" business websites (lets call then "enterprise" websites), this article is completely misleading and it may be worth it to gain a perfect score across all these tools.

Additionally a number of your statements are simply factually false. PageSpeed Insights DOES measure your page speed the same way Pingdom does. It will warn you if the markup takes more than 200ms to download and reduce your score for this. Also image optimization DOES matter and has matter for many, many years (will also be included in scores for classic PageSpeed and YSlow too).

The scores of your sample websites are quite accurate and you have naively assumed that similar load times on a desktop/laptop/server with high speed internet and a decent processor will therefore always be fast load times. Take that website with a 2.7mb download and 55 http requests to a 3 year old mobile phone on 3g internet and watch your load time hit 30 seconds or more! Take the other sample website at 418kb and 23 requests on that same 3 year old mobile phone with 3g internet and the load time will be a tiny fraction of the comparison (probably 25-30%). So the page speed scores are very accurate indeed and DO reflect the overall page speed. Remember as of this last April google is focussing more strongly on mobile!

You state that "Google PageSpeed doesn’t even measure the loading time of your site?" Can you please site the credible source where you got this information?
Thanks

Great google speed insight article. I guess I'm guilty of putting too much emphasis on this metric. Good to know I was wrong for future tests.

Thanks.
Jimmy

Thank you for this post. I have been fighting tooth and nail with clients trying to defend the exact same ideas you posted in this article. I even came up with a hypothesis as to why Google Pagespeed is mis-leading to the general public. Recently I wrote an email to a client to try and help provide more insight to the Google Pagespeed tool.

Client,
To compound on the recent email regarding Google's Pagespeed tool I recently came up with a great way to debunk Google's Pagespeed tool and it's misleading scores.
Try it out for yourself. I figured, hey what would Google's Pagespeed tools show/say about the auto manufacturer websites. I mean it would be a given that these high profile websites must have the best development teams and surely there are no big issues when visiting these websites, right? Well I ran a couple of tests on Ford, Chevy & Dodge. Needless to say the scores would reflect that these sites are completely failing. yet we know they aren't. Both design usability and page loads are just fine on my computer. (* comcast land line, desktop, using safari)

https://developers.google.com/speed/pagespeed/insights/?url=http%3A%2F%2Fwww.ford.com

https://developers.google.com/speed/pagespeed/insights/?url=http%3A%2F%2Fwww.dodge.com%2Fen%2Fchallenger%2F&tab=mobile

https://developers.google.com/speed/pagespeed/insights/?url=http%3A%2F%2Fwww.chevrolet.com

So why would this be the case (the fact they are going failing page speed scores)?

Heres my take on Google's Pagespeed tool. It's a failure right now (in the sense it's being mis-represented). Some businesses & people are out there using it to create a fear that somehow websites are failing or need major changes to become compliant with Google. That somehow a vast overhaul of what you are doing online needs be changed or else you & your website may fail. The fact of the matter is this tool is for Developers and is a tool for developers to utilize to figure out ways to cut server load and reduce server/hosting expense. The real kicker with this so called tool is that some of the points it will deduct you for go against web standards protocol. And Google is part of the web standards initiative so it is mind boggling to me how they (along with microsoft and many other companies) are suppose to push for this so called web standards to make it easier for designers and the end user but then develop this tool which makes recommendations contrary to the so called web standards.

I'm not convinced this tool was ever meant for the general public or general business to business discussion. It has its value & purpose but I think when people start showing the Google Pagespeed tool around like its suppose to provide some sort of insight to folks who aren't developers, it certainly makes the waters murky and more confusing.

As professional web developer I can't agree with most of things written in the article. It is obvius that author of the article never built nothing, or have lack of knowledge on how to properly build a website. While I agree that pagespeed insight does not concentrate around speed only, it does a lot more. Also another thing is I see that author of the article used another "generator" that have very limited approach location, which proves how big amature author is. Ofcourse that if you load a website which server is located in Afganistan and your starting location is Canada ofcourse it will load a lot more. Proves that author of the arzcile is missing some crucial and basic knowledge about networks. Second, for myself I use site analyzer with google insight. Doing things right and by the standards will keep your projects healthy and on top of the class. Others, as the author of the article without basic knoledge on how to properly build a website will whine.

@Ben

If you read this post carefully, you will notice, it not sad to does not care about your health of your webpage. It says, do everything what you can, but after that do not spend more time and money to to try to incrase your page speed to 100m or with 1 point.

This PageSpeed is a bullshit.

Some of my experience, and impressions:

Clients always want everything, fast, good, and cheap. They want to monitor they visitors. What is the best tool for this? Google analytics.

From this point, you are lost, and your site will be never score 100%! It is also true for jQuery.

I am loaded it form googles CDN, and they sad to their own script, to use gzip??? What the heck? It is so ridicuolus.

Javascripts: they always say, to defer / asynch it. It is impossible to. Now I am developing a jquery mobile site. jquery mobile javascript is depends on jquery framework, so you can not load it asynch.

The only way, to earn the 100 points, if you create a simple HTML page with no js and no/very little inline css.

This is also true for AMP pages.

Speed Junky - your http://fastwp.de/ site has a 100/100/97

You should work on prioritizing visual content.

You also aren't using google analytics.

Props to you, though, for having a wordpress site and receiving almost perfect grades.

check out http://iqrco.de

That is the only grade so far I have seen with a 100/100/100 on Google Page Insights.

On GTMetrix it has a 100/99 because it doesn't use a CDN.

This is a terrible article, and it spreads some pretty bad mis-information. Why so focused on load times?

They are far far far from the most important metric. The most important thing for your users is how quickly the site is usable; ie, what pagespeed measures. You need to worry about speedIndex, not page load. Why are wordpress devs so bad at this?

You wonder why pages with long load times get higher scores? Who cares if the site takes 10 seconds to load if it's usable within .5 seconds vs a site that loads in 5 seconds but isn't usable until 3 seconds in? These aren't just made up cases - it's common. And the solutions are easy so why not do them?

TLDR: Perceived performance is the most important thing. Don't block the critical rendering path. Learn to read a waterfall. Load times don't matter.

Read these articles instead to get this nonsense out of your head:

http://www.sitepoint.com/speed-index-measuring-page-load-time-different-way/

http://www.stevesouders.com/blog/2012/02/10/the-performance-golden-rule/

http://www.stevesouders.com/blog/2013/05/13/moving-beyond-window-onload/

https://speedcurve.com/blog/critical-blocking-resources/

@JP

I really hate those sites, what is usable in 0.5 seconds. This is, because site is loading very fast, but not the adverts for example from CDN. And most of the webmasters do not use placeholders. So, when the title of article loaded in 0.5s, I am happy, and I want to click on it. But while I move my finger to the title, and click on it, an ad or a picutre from a previous article is push down my title, and I click on something else accidentally. Then I lost some traffic, I need to push back button, and do the whole procedure again, but this time I am waiting that 5sec to be sure, there are no more element to load. So the "above the fold" is good only, if there are placeholders. But if there are, you will see a big white area.

But unless you are willing for high end google search results you need a high score on pagespeed. Unless I am mistaken.

Thanks to all for sharing their own experiences.

If you read information carefully from Google Page Speed Insights you will find that they don't care about server time response. All they need is your page speed and the user experience. This is one diference between Google and Pingdom Tools.

The truth about Google PageSpeed is that your score matter and you should do the best to get hight score. I'm Front end Developer and I'm specialised in optimize websites for Google Page Speed. For example my website have 91/100, 97/100 hight score, I improve this score to make both users and Google more happy.

In 2016 you will never find websites with low speed or bad code in the first results. You should care about Google Page Speed.

@Dan: Do you really think that Google Bots will take the time to make a Google Page Speed test on all your pages? It will cost them to much money to do that. It's why the Google Page Speed grade can't be care for Google. And actually, the page speed doesn't have any effects on your SEO rank.

Hey Jonathan,

Tx for your reply, we can test this. I will make a page with some poor/medium loading time, and after that I will optimize using Page Speed to get highest score. No other changes. Did you want to guess who's gonna win?

Also, why wp-rocket.me has all the html, css, javascript compressed if page speed doesn’t have any effects on SEO?

If you can have you website faster, do it! users will love this, and if users will have great experience, Google will be happy.

Cheers!

thats not very smart, if the pagespeed is bad the bot will stop before he have seen your fuill side as faster the page so more he can index. if the speed is very slow you get penalties because the user expirience is bad...

Good article. I definitely improved my website quite a bit back when I was new to this kind of stuff by following some of the PageSpeed guidelines, but like mentioned in the article, some are impossible or even ridiculous :-)

nice vision of the Google speed strategy. But I consider it matters, as i'm trying my best to move at least little bit our website http://www.pnnsoft.com/ by for the last 3 years it remains at the same point. We improved everything, but still the Google PageSpeed is low, we cant identify why. I think it is the reasoon a website is moving soooo slowly. I thik so, as the same topic website is mow visible by good keywords, and the website is only 1 year old))) abd the Google PageSpeed is good.

Any suggestions?

Thank you for the step by step guide. Through your guide I was able to achieve good score of avg 96% on pingdom and google page speed. My only concern is with the speed site speed. I have tried both cloudflare and cloudfront and none worked. My question is can we use both of them?

We used the Google Pagespeed Insights service to optimize our website performance on mobile devices. It helped greatly, we've managed to improve user experience greatly.

Thank you very much, I have wasted many time to gain Google Pagespeed score. Now I'm focusing only on Page load time.

Great post Jonathan. It's true, most of us use Google Page Speed Insights as a tool. As Lubos said though, the above the fold load time is more important than the load time of the whole page. Why else would Google tell people to inline the above the fold CSS?

The point is to deliver the best user experience. That is is what Google is aiming for, not the score. Page Speed Insights is a guideline for great site performance, not the wirtten-in-stone law that says your site won't rank if you have a bad score.

There are actually many sites in the first page results with a failing Page Speed score (for now). Test it and see.

Google currently checking the mobile friendly and page speed issue, therefore its really important to improve the user experience. As a web designer, I always give priority on page speed when I create a website. I have few website with page speed score about 90 and I am getting better result.

I usually check how the competition does in Pagespeed insights. I check the first 10 results in Google search.
I rarely find a site with a score over 60 in mobile or 70 in desktop. And the ones that have good score are sites with old design, some are not even mobile friendly (no responsive or mobile site) but they get scores over 60 in the mobile grade.
How on earh it is possible a site that googles finds to be not mobile friendly to have a 70+ score in the pagespeed mobile category is beyond my understanding.
So well.. PageSpeed is just another mean to make people spend their money for nothing. And make the honest developers loosing clients who trust google's wisdom more than common logic...

Try the free website speed tests https://loadfocus.com/website-speed-testing, the best page load test tool I've found so far.

WP-rocket absolutely rocks. My website (www.heirloom.photography) is going 4 times faster !!! Just one question though, how do you know which js files to put at the footer?

Yeah false.. my wordpress site is extremely graphical and jquery reliant and i have 100/100 mobile and desktop. Its not impossible you just need to know client side and server side programming. To many people trying to say they are web designers when they use templates or throw together some spaghetti code they found googling the how to tutorials. For a site like this to say its nearly impossible is scary.

I have done my own testing over 6 months. My site is booming in the serps on mobile and desktop since changing to 100/100 score and that is the only thing i change. Looking at the analytics i can see the change start to climb as google reindexed my changes on each page.

It hit its peak and i went back and got wc3 compliance 100% too and again got a large spike in serps and more traffic again.

Thanks for this post. I find that google makes a hoot and holler mainly about page load speed. I will take note of what you speak about here in this post however and analyze it to see what I can work on for my own website. Thanks for the post.

guys check out our pagespeed https://developers.google.com/speed/pagespeed/insights/?url=codeplay.co.in%2F
any suggestions to increase it more

Your article is misleading. You say Page Speed score does not matter... what you need to make clear is page speed score does not matter for actual speed of the site. It does matter for other aspects, including the fact Google takes it into consideration for ranking. Your article implies it just does not matter at all. So you should make it clear that does not matter for page speed.

Although of course it does, because optimising images, CSS, HTML, increasing cache time, and many other factors, actually WILL result in a faster site :)

Hi Laurence, I am not sure the google bots spiders score our sites using Google Page Speed. In my opinion, the do NOT consider Google Page Speed score, but the REAL speed when they scan the site.

Hi Lucy, thanks for clearing out myths related to Google Page Speed Insights. You're right, it's not the end if we didn't got 100/100 as some issues may not be solved or not in our control e.g. third party stuffs. So, it's best to solve only those issues which is in our control and those who don't affect our website in anyway.

Today I managed to score 98/100 with 100% user experience in both mobile and desktop views on my website http://www.earnext.com

Let's see if it makes a real difference.

I very insightful post on Goggle Speed Test Insights! Very well written and actually helpful.

You may use a service like this
https://jonassebastianohlsson.com/criticalpathcssgenerator/
for finding the render blocking CSS to extract the above the fold css parts, then use them between the head tags. If someone is interesting to see the result check my website, I have implemented it with autoptimize. It gives a better result, and a faster speed.

Hi Lucy, thanks for clearing out myths related to Google Page Speed Insights. You’re right, it’s not the end if we didn’t got 100/100 as some issues may not be solved or not in our control e.g. third party stuffs. So, it’s best to solve only those issues which is in our control and those who don’t affect our website in anyway.

Forget about this page speed. I've seen sites that take ages to load but they rank at the top of Google page 1.

Thank you very helpful article, I've been following of the Google PageSpeed guidelines.
I got 100/100 mobile and 100/100 desktop

https://developers.google.com/speed/pagespeed/insights/?url=https://ideatoz.com/

There is an addon plugin for WP Rocket on the wordpress site that will remove render blocking css by adding Async: "WP Rocket ASYNC CSS"

And also remove render blocking JS: "WP-Rocket Footer JS"

Ok so we can already add JS to footer manually with WP Rocket, but why no option for Async or ability to insert critical css? We have to use other plugins for this.

The really sad thing is that page speed test seems to have absolutely no bearing on organic search results ! ! Just ran a test of the top 3 results (after the ads) on several searches and none of them came close to passing the test ?? Since I am in Ecommerce I am constantly searching for products on Google, but their results are getting worse every week and no matter what they claim, seem to be very much influenced by advertising budgets... Do I really need to be told that Amazon, Ebay, Target, Jet, aliexpress and Walmart have frying pans for sale ? I already knew that ! If i am searching Google I am looking for the alternatives to the obvious !

"Perfect scores aren't possible".
I accomplished it with blogger. It took removing a lot of the native code and using lightweight javascript to accomplish the same effect as heavyweight JQuery and such. Getting a Pagespeed 100% for awhile now, and average reached of 95% to 98% on YSlow on GTMetrix reports. Even reached 100% a time or two for YSlow. Speed ranges from: 0.5 to a couple seconds, max.

This article is wrong

It's easy to have 100/100 on google, and 99/100 on most of website speed tests, or 1 grade !

Just learn how to build a website correctly, and you will have those stats !

When i do a website for a customer, i don't loose my time by trying to get those stats, those stats are natural when the site is building in a good way !

I'm a Computer Graphics researcher and my site strongly depends on images. In my case, the only way to make Google PageSpeed Insight happy about the images is using the "optimized images" it generates itself. The problem is: Googles's dummy image optimizer degrades image quality in many cases and I have many examples to prove it. I will not discuss the tech details in a post comment, but It's so serious that I think it deserves an exclusive article.

This is very very helpful post for me, i was very confuse between google page speed and Gt Matrix tool. Both are showing huge difference in page speed. But now i can belive only on Gt Metrix which showing B grade of speed. Thanks for clearing the doubts.

I reached 91 mobile/95 desktop on google's pagespeed test, and 100/91 on gtmetrix using theme.co's X-theme, wp-rocket and autoptimize. I'm not a developer, and my site isn't fancy, but it's not stripped down, uses jquery and google analytics.js.

https://schecteracademicservices.com/

So it's doable. Page load times .5-.7 sec.

Wp-rocket is awesome, definitely worth the $, but I do WISH that I could defer/async css with wp-rocket, because then I wouldn't need autoptimize to handle that function.

Currently Google PageSpeed Insights is unusable. Shows wrong results.
Launched on February 2017 the tool it buggy now.
The Google team said they are working on it...
Watch pagespeed insights forum.

A Google PageSpeed 100 score has a significant effect on SEO. I've seen many customers, sometimes with a new website, obtain top 10 rankings for premium competitive keywords and often receive free business box promotion on Google mobile (#1 spot in local business, the physical #1 spot on modern Google pages + a large right side box with company details, pictures and more). The reason for this is that Google is increasingly offering users dedicated mobile services, for example to find a local business, and when Google has to select a website for use in their services they will select a website that has the best chance to offer users an optimal (mobile) experience, which is measured by the Google PageSpeed score.

The Google PageSpeed score is a grade that shows how Google perceives the overall reliability, speed and user experience quality of a website. Google's intend is to make money by satisfying searching users. In order to become the primary result in the modern Google, it basically comes down to making Google believe that your website has a higher probability to satisfy the most users for a search term. A Google PageSpeed 100 score is a factor that tells Google that the technical / user experience quality of a website will be optimal so that the chance will be high that users will be satisfied with the result in diverse (complex) conditions that could include mobile device, environment, internet connection speed (history), geographic location and more.

It is true that pagespeed is important.
But for me Google Pagespeed Insight score provides an analysis on how the performance speed of my site. I do not need to get a perfect score, the more important is the real speed of my site satisfying the visitors.
After all, many of the top sites have Google Pagespeed Insight score only 85/100 or less.
Facebook = 68/100 and 88/100
Amazon = 65/100
wikipedia = 86/100 and 94/100

Fun fact 1:

Create a fresh page with a google AMP validated source including just a question mark in the body - yes thats right - pretty muich the boilerplate and and 1 byte for the document. No images, no css no javascript (not allowed anyway).

*drumrole*

Score: 91

That did it for me, screw google pagespeed!

Fun fact 2:

Adding lots of code and several images and javascript files I managed to get a score of 96 which goes against logic given a ? boilerplate gives me constant 91. I have experienced pagerank for being unstable earlier but know it is - how they magically calculate their number is obviously due to some luck in how you stack your elements even if you add to the page which again - as a programmer - I can not have anything to do with such a service as it melts my brain in agony!

Great article. The speed of the site is very important thanks to topic .

Hello from 2017! You can ignore the Law (read Google PageSpeed score) and live by your Own Rules, based on personal conclusions. But only at home. Otherwise you'll get punished. You can also argue that the Earth is square, the sugar is salty and the dogs are able to fly. Who cares?

But if Page Speed Insights is telling you that there's a huge delay in your server response, css and js blocks visible content appearance etc... Imagine your giant page loads in 4.3 sec and (!) first visible data appears only after 3 sec.. users will go elsewhere. It's all about UX nowadays

Nice article, clear up. thanks wp-rockets.

Yes. Even I dont think page speed will be going to have impact on ranking. Google page itself has less page speed LOL!

The speed of the site is very important thanks to topic Great article.

I am slightly skeptical about properly using the Google page speed insight tool as it display the lines of codes to minify the CSS and JS codes to improve the performance of the website. With the use of this Google tool came to know how to improve the page speed of the website. On implementing the same for website http://www.infirays.com has helped to improve the overall loading speed and ultimately rankings. I would say everyone has their own way of experimenting the things with big G.

I agree with everything in this article except the title but only in the case that the big G actually uses the same logic as the GPS tools to grade websites it indexes.

If this is the case, we should actually all BE REALLY CONCERNED because our sites are often being graded unfairly because the tool lacks the proper depth to actually know and understand a real-world human experience. I get upset of the idea that my sites may rank poorly because a tool used to grade it isn't up to the task logically. Funny thing is when the GPS tool is used on the big G's own sites, it doesn't get good grades either half the time. Again, grain of salt yes but if we're being unfairly graded and this impacts our ranking then we should actually be pretty upset about these tools and demand better.

I have sites in which the full visible page load is in low ms but still get outrageous scores in the 60-70 range while using other tools I get extremely high grades. Often the suggestions made by GPS have nothing to do with the actual experience a real human would have.

I lobby to demand that Google fixes the logic to understand how websites in 2017 are built, not just against the most common methods used a few years ago. We have websites in which the DOM is entirely full-duplex javascript applications. Also, the image compression often suggested are of terrible quality yet it complains about a few bytes with big mark down results when it comes to overall score simply because you did not use the "optimized" images they provided. The fact that a few bytes change a score by such large numbers tells me they don't have their logic right.

For example, techniques such as lazy loading or content hidden behind modal triggers often count against you because the tools cannot perceive what the human actually sees vs what is left behind the scenes as part of the user interaction later in the experience.

I'm glad you concur. I have come to the same realization about 'chasing a grade!' The image compression seems to most always be the leading factor of page speed. This, thank god is probably one of the easiest DIY corrections anyone can make! Thanks for the article!

Hi,

This is an article give me some oxygen, since last week I am in huge confusion and trouble after disapproved my google ad sense application . I try to optimize my site as per google insight speed result which was showing 90 for desktop and 74 for mobile. After long try and activate speed booster pack plugin it improves 96 for desktop and 95 for mobile.

But now another issue raised with the appearance of the sites. Can you please suggest whether I revert back to my old position and set up, is it really matter to get the google absence approval? Or any solution further to optimize the appearance issue?

I always thought that the speed of the PageSpeed is the speed of loading the page, thank you, you opened my eyes !!!

Please I have the plugin installed but I keep getting everything wrong on google tests. My pingdom score is B. I don't know if thats Nice. Please can you test and give my website recommendations on what to do. Here is the link www.cybergeak.com . Thanks I really expect a helpful reply from you soon...

I didn't trust google pagespeed test, it's not accurate. If we tried to test "deviantart.com", the score is 1/100, OMG this is the worst score I have ever seen. But if we open the actual site it took 1s to load.

On the other hand, the score of my blog is 50/100, not good but it's better compare to deviantart score, but in real live my blog took 6s to load, which is very slow.

Btw my website is very small only 2000-5000 UV/month, hosted at Linode 4GB plan, I'm using keyCDN and cloudflare. Last year fully load only took 600ms-1s, then I installed SSL and social locker, I think this plugin is very heavy, my website become very slow.

Currently I'm using W3TC, but I'll happy to try another plugin, do you think Wp Rocket plugin can help my page speed? I really missed the fast speed like before.

Thanks :)

Thanks for this awesome article.

Now I understand that Google PageSpeed Insights has no importance for Load time or SEO.

So I am using only WP-Rocket on blog https://www.earngurus.com/ and checking my speed on GTMetrix and Pingdom

Nice article! I wish I could have read this article a bit earlier because significant time has been wasted on Google PageSpeed Insights.

It does indicate some potential issues with the site but really not worth the effort to hit a certain score.

Oh mei, thank god a friend of mine has sent me this article! I was quite a while going nearly nuts with all this speed stuff. Working in all corners on my website, http://www.anettemossbacher.com, to get a Ferrari running, if not a Formula One racing car. Now when I read this, that subject matter is going to be closed. We have 2 websites, my own and an online shop. The online shop runs with WP-Rocket already, it will be more fine tuned. A Cache plugin is needed indeed for websites. For the Leverage browser Cache - Google analytics - there exist a plugin to get rid of it. Honestly I did not see much improvement when using it, it only disappears in the page speed test results! Never mind for such, I my opinion. To make images load fast in a website is a photographers challenge for sure. There are some great tools, yes Photoshop...etc. imigfy for in the WP site... There is a need to get images load fast, with the sacrifice losing on image quality. Bad for a photographer! However, I was so glad to read this article, thanks so much. I told already my friend who sent it to me my Million thanks.
Have a fantastic day and for sure I am now cured of the page speed syndrom :)

Ciao Anette

Nice article but have you check the crawling data after such an upgrade of your score? We have seen a significant increase of crawling on our website may be due also to the change of server too. I will survey the data for a couple of weeks and report the results here. NB we have removed the "Eliminate render-blocking JavaScript and CSS in above-the-fold content" at the moment so the score drop to 87/100. And for an unknown reason, we have a different score for mobile if someone has an explanation for this? Check the website on pagespeed http://dlcompare.fr and give me your toughts.

That was real help. I was chasing the speed grade like mad.. Thanks I found your article.

This is a very useful post. I do use pingdom tool, gt matrix and google page insights to analyze my blogs

thank you for the tips and heads up

Great Article. I found this whilst looking for Page Speed Insights, don't think I will bother going there now lol

Focus on the actual site load time of a site, since Google PageSpeed is just based on the rules that are set.

https://developers.google.com/speed/docs/insights/rules

Great article, I'm using Google fonts on my site and insights is coming back saying that the css needs to be optimised! You'd think they'd make sure their own stuff was done properly if they are going to penalise websites that use it.

you are not right. I got for https://beerm-ksa.com 100/100 for first page and optimized most landholdings . This is new website and it is ranking fast . If you get 100 your page will be faster just because less http requests and smaller code.

That was real help. I was chasing the speed grade like mad.. Thanks I found your article.

Great article, I’m using Google fonts on my site and insights is coming back saying that the css needs to be optimised! You’d think they’d make sure their own stuff was done properly if they are going to penalise websites that use it.

The website speed is really matter that's why we had optimise our website. On PageSpeed Insights we have 100% score on both mobile and desktop. And yes it is difficult to do it but not impossible.

Google Pagespeed test tool is not accurate, i don't trust it one bit. Other tools are giving my website here CyracksInternetBiz 100% while google pagespeed is reporting a little bit less and sometime below what i expected. Their test result is not steady on my blog. It fluctuate up and down. What other tool do you recommend please?

First of all. I understand what the author is trying to tell us here, BUT this why it matters and why I want the beste Pagespeed score. Google is the biggest company in the world. Everybody knows Google. It's easy to sell to my customers. Pingdom, GTMatrix bla bla....is well....nobody (I'm sorry, you're services is GREAT, but you know what I mean...). So, that's why I can't agree.

We have been struggling with this for a little while, the balance between a good looking design and speed is a real challenge on our Electric Heater site, but we have been trying to use lots of different tools such as GT Metrix to get a good page speed. Every time we add facebook tracking or another SEO tool the speed drops, so it's a constant review and improve process.

Surly Google uses the metrics in this tool for it's ranking, so surly it matters? Even if we do spend hours trying to get another few percent on the score.

Page speed does matter, especially on mobile. Large companies like Amazon wrestle to improve their page loading time, even by 0.5 seconds. Page speed means also to improve their user experience. Annually they recorded a consistent sale increase just from improving page loading time. Small companies, local businesses can search for wordpress plugins to optimise their images.

Hi, you are not right. I got for https://sosdienests.lv/ 100/100 for first page and otpimised most landingapges. This is new website and it is ranking fast . If you get 100 your page will be faster just because less http requests and smaller code. ;)

Hey Jonathan,

This 100% true. The 100/100 will just affect the loading speed by elevating it, but still not going to give you a good page speed. I tried it out on my blog but I got to know that the page speed also can be reduced when on HTTP but otherwise in HTTPS.

This is the most details article about Google Page Speed. Good work.

@Lucy @Jonathan ~ you have my email, so sent me an email, I'll show you how.

Some points in this article are wrong. I worry that some developers can't code very well. Mostly bad coding at WordPress themes. In order to reach highest score in Google Pagespeed, 90/100 and above, is very very easy. Trust me, I'll give you case study.

And, of course WP Rocket is one of the best plugin for speeding WordPress theme. (based on my friend's experiences)

Cheers :)

I completely disagree with your article and my Google dev team would also disagree too. Our clients site speed test come out at 97-98 across the board. Maybe its the way you develop your sites. Slamming the tools that scores sites using google search (90% of searches, as you know)

Someone told me that pagespeed helps to rank faster and did everything to make my site speed better but there is no bit change thanks for explaining this topic with us this helps me to understand page speed on seo well

This article is almost three years old. Are there newer insights or is this still relevant?

This is right Google Page Speed Insights do not tell you about actual site speed, it's simply analyze site code and will be showing results them, but this is not your real site speed. According to Google Page Speed Insights, the Google analytic homepage score is 93/100 for the desktop, but Google analytic is opening slow, finally outcome is this is not true.

Hence, we need to score on other tools like Gtmetrix, etc. But we should make our site faster to provide better user experience. Most internet users abandon a website that takes more than 3 seconds to load. Inside of this, some web pages lost potential revenue cause of slow speed even after the opened page.

Hi Lucy, thanks for clearing out myths related to Google Page Speed Insights. You’re right, it’s not the end if we didn’t got 100/100 as some issues may not be solved or not in our control e.g. third party stuffs. So, it’s best to solve only those issues which is in our control and those who don’t affect our website in anyway.

thanks for this enlightening post

The comments in this post are just as helpful as the post itself! Great informative article Lucy, well done :)

Very useful Article for improving PageSpeed Insight Score .

Thank you Lucy. Because I only started my website just over a week ago and I am one of the ones that has developed tunnel vision regarding Google's Insghts test. Yes, I must have saved over 50MB scaling down my photos, but to be hones another online tutorial told me to do it first - Google's test simply confirmed it.

It's other website speed test pages for me now, I cannot go crazy chasing a grade, as you so aptly describe it.

Anyway, many thanks for this article.

Oh and greetings from the Czech Republic. ?

Thank you for this great post. I was really blinded by Google, and as you mentioned, sometimes it asks impossible things to do.
Thank You again.

I don't use Pagespeed anymore after discovering Google Lighthouse (the best technical analytical tool available!).

Sometimes it's really hard to explain to clients why do they need to increase their page speed. Next time I'll send them this article. Thank you for it)

Many of my clients show me google page speed tool or gtmetrix for speed result of their website. And even after optimizing their site and making boosting page speed, sometimes they question my effort after what they see on google tool. Thanks to this article, from now on, I will simply share this link with them once they doubt my speed optimization effort!
I use wprocket for all of my sites, and I love the result!
Thanks!

I agree! There is indeed a big misconception among clients that scores on this tool are a perfect way of judging the performance of a website. They don't understand how it works and the fact that only WebPageTest.org measures real speed for real users. All others are just best practices tools that are useful for performing an optimization, but not for judging the results of one.

thanks for this article The website speed is really matter that’s why we had optimise our website. On PageSpeed Insights we have 100% score on both mobile and desktop. And yes it is difficult to do it but not impossible.

I never care about it, just test it with gtmetrix

I decided to get my site sped up just for user purposes but then did check in Pingdom, GTMetrix and Webpagetest.org and each show that it is pretty quick. I went for a minimalist theme because I don't need big images to explain a point and kept text down - again, I don't need lots of text to explain what I offer.

But I do use the 3 tools to test because like when I audit a website, I like to have as much information as possible, which means not limiting my data. If anyone wants to check it out, www.iqseo.org - but I would suggest if you are serious about this, then webpagetest.org is the main site to believe.

I regularly use to visit your site to collect some new idea from your Article and usually found it here.
Awesome representing way and full of information.
Thanks

Hi! I've used these guidelines for PageSpeed for my website and it helped deliver good results. The bottom line is that one should just focus on improving load times on web pages, and not think too much about the Page speed scores on different tools. Each has a different metric, and therefore it's best to stick to one.

For most of the high-competition search queries, if you analyze the page load-time of the pages ranking on page 1, we do find a strong correlation between the page speed and rankings. It also makes sense to rank faster loading websites (of course if they are relevant) on top of slower ones as it provided much better user experience.

Why the images of your site are 'lazyload'? Does this have an impact on seo?

Thanks for sharing this information keep it up

Well described post. Thanks for sharing this useful information.

Hey, I currently use wp rocket on my blog and Page speed is telling me a lot of things that I don't seem to understand.
Could anyone please give me helpful recommendations to how I can fix these problems? It looks like really technical web development challenges.
My url is here for anyone who is willing to help check and give me a useful response to how I can fix things: https://techiewiz.com
I will be waiting for helpful responses!
Thank you.

so, I did as a test Autoptimize and HummingBird cache, average score of 67-71% over 3 hours. Then tested Wp-Rocket, 0% (yes 0!!) to a massive 2% average. Not sure whats going on there

"School grades are not an indicator of intelligence!" So why did all the brainy kids get As and the thick kids Es? :)

The reason why benchmarks vary is because if you're on a shared host, times will fluctuate wildly. You can do a test at peak time and get a slower download than when it's quiet.

So grades do matter, although they are an indicator of potential performance all things being equal. Use them as a barometer alongside actual download times.

Not forgetting that in the West we take Internet speed for granted, whereas some less fortunate countries are still on painfully slow connections where a fast website matters more than ever. It's not just 1 - 3 seconds, you could be talking 30 seconds plus!

Unfortunately what this article missed and dismisses out of hand is that Google use the FCP - First Contentful Paint - metric as a ranking signal. You should absolutely care about that. Your users will as it affects their experience of the site.

Ha, I've been saying this for years -- at least pertaining to websites in the U.S. ...that GPSI is a waste of time. Never mind WP.. with SSDs being employed in Apache servers, and most wireless networks moving away from 3G, to 4G, and soon to 5G, bloated sites are less a concern anyway.

Absolutely Correct, I really appreciate your Blog Work. Actually, I was also worried because GTmetrix show my Website Speed score as 96 with Under 2 Second Loading without Caching whereas Google Page Insights Showed the score of 12. At That point, I realised, Its their mistake in making the Tool.

my website was coming up number one on Google for many years now. I have spent some time now in the last 2 months getting a 99% A score on GTmetrix and 80% on Google Speed Test - But my main competitor who gets a F on GTmetrix and 4% on Goole Page Speed has now moved on top of me??? Is this a hoax?

My site loads in .7s and their site loads in 12 seconds ??? and now they are above me ???

Crazy world we live in Google - maybe I should go back to one of my old slow backups?

Confused!
