We’re going to focus on this super popular tool. We’ll show you how to use it and understand its results, and how to fix its most common recommendations. We’ll also suggest some alternative testing tools.
At WP Rocket, we firmly believe that optimizing the web performance of your site is not something that should be left in the hands of a single tool. There are a number of excellent and free performance testing tools so take advantage of them.
Google launched the first version of PageSpeed Insights around 2013. They wanted to provide a tool for performance analysis and make it usable for a broader audience.
For this purpose, they built a tool that returns a performance score and provides suggestions on how to improve it. Auditing is available for both desktop, and mobile devices.
Over the years, PageSpeed Insights (also referred to as PSI) evolved to become one of the most popular performance testing tools. Its scores are easy to read, and its suggestions are useful to understand what can be improved on your site.
Our PageSpeed Insights 2019 Guide will take you through the secrets of this essential tool, and will show how to make the most of it.
The scoring system at the core of PageSpeed Insights is probably one of the reasons it became so popular.
Getting a grasp of the health state of your website is effortless with PSI:
Since the end of 2018, PageSpeed Insights is powered by another tool from the Google family: Lighthouse.
While the scoring system didn’t change its appearance, several under-the-hood mechanisms modified the way a PSI report should be read.
That’s why we wrote a guide on how to read the new PageSpeed audit powered by Lighthouse.
On the other hand, we can’t stress this enough: it’s imperative to use PageSpeed Insights as only one of the tools to assess the health of your website’s performance.
PSI scores shouldn’t give you headaches. They’re not a universal truth.
Our guide on why you shouldn’t care about PageSpeed scores explains why.
A PageSpeed report usually contains several suggestions. But, if you don’t feel comfortable with the technicalities of website development, they can cause confusion, and make you feel at a loss.
With our guide, Google PageSpeed Insights recommendations explained in plain English we provide the basis to understanding the most common PSI suggestions.
We’ll see how to interpret their meaning, what the easiest fixes are, and when you shouldn’t worry too much about them. Above all, you’ll understand why getting a 100% PageSpeed Insights score may not be a realistic expectation.
Now that you know all the secrets concerning PageSpeed Insights, you can go on and get to know its alternatives.
There are several excellent speed testing tools out there, and the WP Rocket team uses some of them daily.
Here are seven of our favorites:
You can play with them, compare their results, (knowing that sometimes they can differ) and learn how to make the most of them to assess the real performance of your site.
For more details, check out our guide about page speed optimization for WordPress.
One of our favorite alternatives to PageSpeed Insights is GTMetrix. We use regularly to assess the performance of our customers’ websites.
GTMetrix is a straightforward tool that will give you a complete overview of your site’s speed.
It doesn’t rely on scores, and it starts with the most fundamental metric of all: loading time expressed in seconds. This indicator, more than any rating or recommendation, is the real starting point of any performance audit as well as a ranking factor for Google.
In our guide about understanding GTMetrix, we’ll provide all the necessary details to familiarize you with this tool.
You’ll see how to customize your GTMetrix report according to the characteristics of your site’s environment. It will also help you become an expert in the interpretation of its tabs and metrics.
Learning how to use performance testing tools to assess the health of your site is a crucial asset. Once you understand how to read their reports, improving scores, and fixing their recommendations will become a lot easier.
WP Rocket is one of the tools that will help you achieve this goal efficiently and without stressing too much on configuration settings.
Our plugin is all about caching and optimization. After installing it, your website will immediately, and automatically benefit from 80% of web performance best practices including:
PageSpeed Insights will love this and reward your site immediately, improving its performance score.
Then, you have WP Rocket’s optional settings. They’re not mandatory since your website will be faster already, even if you don’t try them.
Proper use of these settings will not only make your site blazing fast, but will also boost its performance. You’ll achieve faster page speeds, better SEO rankings, and the best scores in PageSpeed Insights. (or other performance tools)
Most of the WP Rocket’s options that will make PageSpeed Insights fall in love with your site are included in the File Optimization tab.
PageSpeed Insights is particularly sensitive to the way files are loading on a page. A couple of its trickiest recommendations are called Eliminate Render-Blocking Resources, and Defer Unused CSS.
These refer to the fact that it’s recommended to delay (defer) the loading of non-critical files until the browser is done rendering the page.
WP Rocket helps you to solve this puzzle thanks to the options labeled as Optimize CSS Delivery.
On the other hand, the Media tab contains the options that will fix PSI recommendations related to images like Defer offscreen images.
With WP Rocket, we’re striving to make the web a more sustainable place with faster, and better performing web pages.
