PageSpeed Insights, test website performance

PageSpeed Insights is a powerful tool that allows website owners to analyze the performance of their websites and identify areas for improvement. This tool is available for free from Google and can be used by anyone, regardless of their technical expertise.

In this article, we will explore the importance of PageSpeed Insights, how it works, and the steps you can take to improve the performance of your website.

What is PageSpeed Insights?

PageSpeed Insights is a tool created by Google that analyzes the performance of a website and provides suggestions for improving its speed and usability. The tool measures two key metrics:

  • First Contentful Paint (FCP) and
  • Largest Contentful Paint (LCP).

FCP is the time it takes for the first piece of content to appear on the screen when a user navigates to a website. LCP is the time it takes for the largest piece of content to appear on the screen. Both of these metrics are important because they directly impact the user experience of a website.

If a website takes too long to load, users are more likely to leave and go to a competitor’s site. Additionally, Google uses page speed as a ranking factor, so a slow website can negatively impact your search engine rankings.

PageSpeed Insights Metrics

  • First Contentful Paint – First Contentful Paint marks the time at which the first text or image is painted.
  • Largest Contentful Paint – Largest Contentful Paint marks the time at which the largest text or image is painted.
  • Total Blocking Time – Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
  • Cumulative Layout Shift – Cumulative Layout Shift measures the movement of visible elements within the viewport.
  • Speed Index – Speed Index shows how quickly the contents of a page are visibly populated.

How does PageSpeed Insights work?

PageSpeed Insights works by analyzing the content and structure of a website and providing a score based on how quickly the website loads. The tool provides two scores: one for mobile devices and one for desktop devices.

To use PageSpeed Insights, simply enter the URL of your website into the tool and click “Analyze”. The tool will then analyze the website and provide a score out of 100. The higher the score, the faster the website is considered to be.

In addition to the overall score, PageSpeed Insights provides a detailed report with suggestions for improving the performance of the website and SEO. The report includes information about how long it takes for each element of the website to load, as well as suggestions for how to optimize each element for faster loading times.

How to improve your PageSpeed Insights score

Improving your PageSpeed Insights score can be a complex process, but there are a few key areas to focus on:

Optimize images: Images are often one of the biggest culprits when it comes to slow-loading websites. To improve the performance of your website, make sure that all images are optimized for the web. This means compressing the file size of each image without sacrificing quality.

Minimize HTTP requests: Every time a user navigates to a website, their browser sends a request to the server to retrieve the necessary files. The more files that need to be retrieved, the longer the website will take to load. To minimize HTTP requests, make sure that your website is streamlined and only includes the necessary files.

Use a content delivery network (CDN): A CDN is a network of servers located around the world that can be used to deliver content more quickly to users. By using a CDN, you can reduce the amount of time it takes for your website to load, particularly for users who are located far away from your server.

Optimize code: The code that runs your website can have a significant impact on its performance. To optimize your code, make sure that it is clean and efficient, and eliminate any unnecessary code that is slowing down your website.

Reduce server response time: Server response time is the amount of time it takes for the server to respond to a user’s request. To reduce server response time, make sure that your server is running efficiently and that all unnecessary processes are disabled.


PageSpeed Insights is an invaluable tool for website owners who are looking to improve the performance of their website. By analyzing key metrics and providing detailed suggestions for improvement, the tool can help you identify areas of your website that need attention
