As a website owner, you want your website to perform well in search engines and provide a smooth user experience. Google PageSpeed Insights is a tool that measures how well your website performs in terms of speed and provides recommendations for improvement. A high PageSpeed Insights score is crucial for improving user experience and increasing search engine rankings. In this article, we'll discuss which metrics matter and provide some tips and strategies for achieving a high PageSpeed Insights score.

Which metrics matter in Google PageSpeed Insights?

Google PageSpeed Insights is a tool that evaluates the performance of a website based on a set of metrics, providing an overall score and specific recommendations for improvement.

  1. Largest Contentful Paint (LCP): This measures the time it takes for the largest content element on your website to load. This could be an image, video, or any other type of media.
  2. First Contentful Paint (FCP): This measures the time it takes for the first piece of content to load on the page, such as text or images.
  3. Cumulative Layout Shift (CLS): This measures how much your website's content shifts during loading. This could happen when elements on your website move due to ads or slow-loading images.
  4. Time to Interactive (TTI): This measures the time it takes for the website to become fully interactive and responsive to user input.
  5. Total Blocking Time (TBT): This measures the amount of time that the website is unresponsive to user input due to long-running JavaScript or other processes.
  6. Speed Index: This measures how quickly the content on the page becomes visually complete and stable.

All of these metrics are important to consider when optimizing your website for speed and user experience. By analyzing each metric, you can identify areas that need improvement and make the necessary adjustments to achieve a high PageSpeed Insights score.

Tips and Strategies for Achieving a High PageSpeed Insights Score

Here are some tips and strategies to improve your PageSpeed Insights score:

1. Optimize Images

Images are an essential part of any website, but they can also be the reason why your website loads slowly. You can optimize images by compressing them and reducing their size without sacrificing quality. You can use free online tools like TinyPNG,, or Squoosh to optimize your images.

2. Minimize HTTP Requests

Each time your website loads, it sends HTTP requests to the server for resources like images, CSS, and JavaScript files. The more requests your website makes, the longer it takes to load. You can minimize HTTP requests by reducing the number of images, using CSS sprites, or minifying your JavaScript and CSS files.

3. Use a Content Delivery Network (CDN)

A CDN is a network of servers that store and distribute your website's content across the world. By using a CDN, your website's content can load faster from a server that's geographically closer to the user. Cloudflare, Amazon CloudFront, and Akamai are popular CDNs that you can use.

4. Enable Browser Caching

When a user visits your website, their browser stores the website's files in its cache. By enabling browser caching, you can tell the browser how long it should store your website's files in its cache. This can reduce the number of HTTP requests and speed up your website's load time.

5. Use a Fast Web Host

The web hosting provider you choose can significantly impact your website's speed. A fast web host can reduce server response time and improve your website's load time.


Google PageSpeed Insights is a valuable tool that can help you improve your website's speed and user experience. By focusing on the LCP and CLS metrics and implementing the tips and strategies we've discussed, you can achieve a high PageSpeed Insights score and improve your website's performance. Remember that a high PageSpeed Insights score not only benefits your users but also improves your search engine rankings.
