A 100/100 score in PageSpeed Insights is the holy grail of performance optimization. If you achieve that score, your site will load lightning fast, which is a huge advantage for SEO and conversion rate optimization. But how can you actually get a perfect score on Google PageSpeed? Is it even possible to optimize your site so much that it gets 100/100? Will the speed benefit really be noticeable? The answer to all these questions is: yes!

PageSpeed Insights is a very important tool for any website or blog. It’s also one of the most misunderstood tools on the web.

Many people misunderstand how Google PageSpeed works and how to fix their PageSpeed scores. Granted, there are some things that you can do to improve your PageSpeed score. But there are also some myths that need to be debunked.

An Introduction to Google PageSpeed Insights

Google PageSpeed insight provides an in-depth analysis of the web page’s performance and suggestions to improve it. This tool helps us in understanding how well our website is performing, which optimization techniques we can follow to improve performance and ultimately rank higher in search engine results.

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):


The Truth About Scoring 100/100 in Google PageSpeed Insights

Google PageSpeed Insights is one of the most important tools any website owner should pay attention to. It keeps track of how fast your site loads and gives suggestions on improving load time. Since speed is a ranking factor in Google’s algorithm, you want to make sure your website isn’t slowing down users, and if it is, you want to fix that as soon as possible.

While you should certainly strive to improve your website’s loading times as much as possible, getting a 100/100 in Google PageSpeed Insights isn’t actually that important. For starters, it’s not even the be-all-end-all test for performance.

You can also run tests on platforms such as GTmetrix (which combines your scores from PageSpeed Insights and YSlow) and WebPageTest. Chances are, your scores across these different tools won’t match exactly, which shows you how arbitrary these numbers can be.

What really matters is the actual speed of your website.

How Google Uses PageSpeed Insights

Google uses PageSpeed Insights internally to help their webmasters to optimize their websites. If you create a good website according to Google’s standards, then they will rank your site higher in the search results. Most Google search ranking factors are taken into consideration by PageSpeed Insights. As an example, Google values deep links over general links ( vs

Google PageSpeed Insights Recommendations

Google PageSpeed Insights has become a standard for measuring the performance of web pages. It is an essential tool for any website owner to ensure that their site is performing efficiently.

Google PageSpeed Insights contains a set of recommendations based on best practices to help developers improve page load time. This article explains what each recommendation means and how to implement it, as well as provides code examples using PHP, JavaScript, and HTML.

1. Eliminate Render-Blocking Resources

This is one of the recommendations from Google pagespeed insights. Eliminating render-blocking resources refers to JavaScript and CSS scripts that are preventing your page from loading quickly. The visitor’s browser has to download and process these files before it can display the rest of the page, so having a lot of them ‘above the fold’ can negatively impact your site’s speed.

When it comes to Google, there are two solutions to consider when it comes to this.

  • If you don’t have a lot of JavaScript or CSS, you can inline them to get rid of this warning. This process refers to incorporating your JavaScript and/or CSS into your HTML file. You can do this with a plugin like WpRocket.
  • The other option is to defer your JavaScript. This attribute downloads your JavaScript file during HTML parsing, but only executes it after the parsing is complete. Also, scripts with this attribute execute in order of appearance on the page.

2. Avoid Chaining Critical Requests

This has to do with the Critical Rendering Path (CRP) and how browsers load your pages. Certain elements – such as the JavaScript and CSS we discussed above – must be loaded completely before your page becomes visible.

It’s important to note that there’s not a magic number of critical request chains that you need to work down to. Google PageSpeed Insights doesn’t count this audit as ‘passed’ or ‘failed’, unlike many of its other recommendations. This information is simply made available to help you improve loading times.

3. Keep Request Counts Low and Transfer Sizes Small

The more requests browsers have to make to load your pages, and the larger the resources your server returns in response, the longer your website takes to load. You need to minimize the number of required requests and decrease the size of your resources.

You can :

  • Maximum image sizes
  • The number of web fonts used
  • How many external resources you call to
  • The size of scripts and frameworks

4. Minify CSS

The CSS files often are larger than they actually need to be this is to make it easy for humans to read. Minifying your CSS is the process of condensing your files by eliminating unnecessary characters, spaces, and duplications. 

5. Minify JavaScript

Just like CSS, modification applies to javascript too.

WP Rocket can handle this task for your WordPress site well.

6. Remove Unused CSS

f there’s CSS on your site that isn’t actually useful, it’s putting an unnecessary drain on your performance the reason why Google recommends removing them.

The solution here is essentially the same as that for eliminating render-blocking CSS. You can inline or defer styles in whatever way makes the most sense for your pages. You can also use a tool such as Chrome DevTools to find unused CSS that needs to be optimized.

7. Reduce JavaScript Execution Time

JavaScript execution is often the most prominent contributor to main-thread work.

8. Properly Size Images

Media files such as images can be a real drag on your site’s performance. Properly sizing them is a simple way to reduce your loading times.

If your page includes images that are larger than they need to be, CSS is used to resize them appropriately. This takes longer than simply loading the images at the right size initially, therefore impacting your page’s performance.

Google PageSpeed Insights should be a staple in your webmaster toolbox. However, fixating on your score and obsessing overreaching the coveted 100/100 probably isn’t the best use of your time. It may take you away from other important tasks that could provide more significant benefits.
