PageSpeed Insights is a tool developed by Google that allows you to analyze the performance of a webpage and receive recommendations for improving its speed. It provides a score based on how well a page performs on a set of performance metrics, as well as specific suggestions for optimizing the page’s performance.
To use PageSpeed Insights, you simply enter the URL of the webpage you want to analyze and the tool will provide a report with your page’s performance score and recommendations for improvement. The recommendations are grouped into categories such as “Eliminate render-blocking resources,” “Optimize images,” and “Minimize JavaScript execution time,” and provide specific actions you can take to improve the page’s performance.
PageSpeed Insights can be a useful tool for web developers and website owners who want to improve the performance of their websites. It is particularly useful for identifying and fixing common performance issues that can slow down a webpage.
