Tips to improve Google page speed insights

Eliminate Render-Blocking Resources

The tool PageSpeed Insights provides this recommendation frequently. A slow-loading page us caused by JavaScript and CSS scripts. 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. Google provides two solutions for solving this problem. 

When working with fewer resources, it’s a good idea to use inline CSS or JavaScript scripts. Plugins are required to integrate JavaScript and CSS into your HTML file. Sadly, this approach isn’t appropriate for tiny websites.

You can postpone using JavaScript as well. If you choose this option, the JavaScript file is downloaded while the HTML is being parsed, but it won’t function until the parsing is finished.

Minify JavaScript

You should minify your JavaScript files in the same manner that you would your CSS files to minimize their size. Minifying JavaScript involves removing unnecessary characters like white space comments, and line breaks from the code while preserving its functionality. WordPress plugins can be used to reduce the payload size and parse time for JavaScript files by minifying them. This can also be done via the built-in process. 

Remove Unused CSS

Any code in your stylesheet is content that has to be loaded for your page to become visible to users. The performance of your website loading speed will be adversely affected if CSS is not used. As a result, you ought to get rid of any unnecessary CSS. 

If there’s CSS on your site that isn’t useful, it’s putting an unnecessary drain on your performance. 

It is the same process as eliminating CSS that blocks rendering. Your web pages can be styled inline or deferred in a way that suits you. You can also use tools such as Chrome DevTools to discover and optimize unused CSS.

Reduce JavaScript Execution Time

The most notable source of work for the main thread is frequently the execution of JavaScript.  It may be the most important aspect influencing the functionality of your website, and speed is the primary factor influencing functionality. Google PageSpeed insights state that you should shorten the execution time independently so that you are notified if it significantly affects the speed of your website.

Reduce TTFB Latency

The Time to First Byte (TTFB) indication on a browser shows how long it takes for the server to respond to a request and return the first byte of data. TTFB directly affects how quickly your page loads.

While this isn’t the same as your overall site speed, having a low TTFB is understandably good for your site’s performance.

For this reason, Google recommends reducing your server time.

Enable Text Compression

It is recommended that you compress your files using GZIP. Text compression may already be enabled on some servers. You can follow the guidelines even though it isn’t activated automatically on your website with a few different alternatives.

A plugin with GZIP compression is available. WP Rocket is a fantastic choice if utilizing a premium plugin is acceptable to you.

Alternatively, you can compress your website’s text manually. 

Serve Static Assets With An Efficient Caching Policy

This is a warning about caching in Google Page Speed Insight. With WordPress, caching can be applied using plugins. You can also make use of any cache that your hosting provider has provided.

Make sure your hosting provider enables caching on their servers. Once caching is enabled, you should verify its efficiency. Periodically, your browser should automatically clear its cache and add fresh content. Plugins are the most popular method used by WordPress websites to implement caching. W3 Total Cache and WP Rocket are well-liked choices.
