Google PageSpeed Insights is without a doubt a useful tool for webmasters, developers, and site owners of all types. However, we’ve noticed that a lot of people spend hours obsessing over optimizing their sites, in order to try and score 100/100 on this test.

The truth is that this isn’t how Google PageSpeed Insights is meant to be used, nor is it a worthwhile pursuit. When you focus on implementing the platform’s recommendations instead of zeroing in on the number at the top of the page, you’ll be creating a lot more benefits for your site.

This post is a comprehensive guide to using Google PageSpeed Insights to your best advantage. We’ll cover how Google uses your score, as well as how to incorporate the recommendations you receive.

Let’s get started!

What Is Google’s PageSpeed Insights?

Google PageSpeed Insights is a tool used for testing website performance. You can enter any URL and have it analyzed.

Google then provides an overall score out of 100 for the website you’ve tested, based on several performance optimization best practices.

Along with this result, you’ll also see several recommendations from Google on how to improve your performance (and therefore, your PageSpeed Insights score as well).

As of 2018, PageSpeed Insights scores are calculated via Lighthouse, Google’s open source, automated tool for improving the overall quality of web pages. This platform can evaluate all sorts of factors, including performance, accessibility, progressive web apps, and more.

To see Lighthouse’s comprehensive assessment of your site, you can use Google’s Measure tool:

In addition to conducting a performance audit much like the one Google PageSpeed Insights runs, you’ll get scores for accessibility, best practices, and Search Engine Optimization (SEO).
