PageSpeed Insight Tool by Google | How to Increase the PageSpeed Score of Your WordPress Website

PageSpeed Insights is an essential tool by Google. It analyzes your website’s content both on mobile and desktop. And gives you important suggestions that can help you improve the speed of your website pages.

It gives a score after reviewing your page’s result. That is called as PageSpeed Score. A score of 90 or higher is considered fast. a score between 50 to 90 is considered average and under 50 is slow. Also, it estimates how much faster your website pages will become after performing the changes.

If you can implement the changes it recommends, the website will be able to perform better, the user experience will increase so that the website can rank higher on the results page of the search engine.

What are the other tools to measure the PageSpeed score?

Other tools can do the same as Google PageSpeed Insights does. These are Pingdom & GTMetrix. We can also try these for measuring the PageSpeed score and checking the areas of improvement.

We can rely on these two websites, but you shouldn’t forget PageSpeed Insights. As it gives the key suggestions for your website improvements.

How to fix these issues

1. Serve images in next-gen formats

Image Compression Suggestions - How to Increase the PageSpeed Score of Your WordPress Website

Images are a common problem for most of the websites. As the size of the images is more, it makes the web page load slower.

PageSpeed Insights suggests you upload images on formats like JPEG 2000, JPEG XR, and WebP. These formats provide better compression means less size occupancy in your website than PNG or JPEG. It means faster downloads and lower consumption of data.

Also, this warning can be resolved by uploading images after compressing. We use TinyJPG to compress pictures. It reduces the file size without compromising on the quality.

Several plugins can help convert and optimize images, These plugins are

  • Imagify – WebP & Image Compression and Optimization
  • Autoptimize
  • WebP Express
  • Image optimization & Lazy Load by Optimole
  • Smush Image Optimization, Compression, and Lazy Load
  • EWWW Image Optimizer

After optimizing and compressing the images, use it on your website and you will see a better PageSpeed score. Now let’s move to our next suggestion.

Plugins can add additional CSS to your website. And the CSS takes time to load, which increases the loading time of the page. We can fix this by removing unused plugins/apps from your website. Also, the above plugins can help to minimize and optimize the CSS and improve the PageSpeed score of your website.

4. Properly size images

Properly size images

We need to change the size of the images to the correct responsive size, keeping all the devices in mind. If your image is larger, it will not load properly, resulting in wasted bytes and slowing down the loading time of your webpage.

To keep a proper image size, we use plugins like

  • WP Paint
  • WordPress Image Editor
  • DigiWidgets

5. Serve static assets with an efficient cache policy

Serve static assets with an efficient cache policy

It is one of the crucial factors for improving the PageSpeed score. We can fix this issue by caching some elements of our website. We can define the time limit for various parts like codes, style sheets & various types of images. And, for frequent visitors, a longer cache life can speed up the website.

Here are some plugins that can help to cache our website:

  • W3 Total Cache
  • LiteSpeed Cache
  • WP Fastest Cache
  • WP-Optimize – Clean, Compress, Cache

You may find some more suggestions, such as Reduce JavaScript execution time, Minimize main-thread work. These are related to JavaScript and CSS and can be optimized and fixed using the above-mentioned plugins in the No.2 section.
