Google PageSpeed Insights is a tool developed by Google that analyzes the performance of web pages on both mobile and desktop devices. It evaluates the page’s loading speed, user experience, and other technical aspects that affect a website’s performance.
When you enter a website’s URL into the PageSpeed Insights tool, it provides a score ranging from 0 to 100 for both mobile and desktop versions of the website. The tool also offers suggestions for improving the website’s performance, such as optimizing images, reducing server response time, and enabling browser caching.
PageSpeed Insights takes into account various factors that affect a website’s loading speed, such as server configuration, page structure, and the size and format of images and other media files. By optimizing these factors, website owners can improve their website’s performance and provide a better user experience for their visitors.
Overall, Google PageSpeed Insights is a useful tool for website owners who want to improve their website’s performance and user experience, as well as for developers who want to optimize their code and server configurations.
In addition to providing a score and suggestions for improvement, PageSpeed Insights also offers detailed information about the different aspects of a website’s performance. This includes:
- First Contentful Paint (FCP): This measures the time it takes for the first piece of content to appear on a user’s screen. A faster FCP means users can start interacting with the website sooner.
- Speed Index: This measures how quickly the visual content of a page is displayed. A lower score means that the content appears faster.
- Time to Interactive (TTI): This measures the time it takes for a page to become fully interactive, including the ability to click on links and interact with forms.
- Total Blocking Time (TBT): This measures the time it takes for a page to become responsive to user input. A lower score means that users can interact with the website more quickly.
- Cumulative Layout Shift (CLS): This measures the visual stability of a website, specifically whether elements on the page move around unexpectedly as the page loads.
By analyzing these factors, website owners and developers can identify specific areas where their website’s performance can be improved, and implement changes to make their website faster and more user-friendly.
