Examine the website's performance in terms of speed, identify any bottlenecks, and resolve them so that both users and search engines can access it quickly and easily.
The PageSpeed Insights Checker provides information, diagnostics, and recommendations on how the page may be improved. It measures how well a webpage performs on desktop and mobile devices. The performance of the page is summarised in a circular chart at the top of the report, which is followed by additional information and a screenshot of the page's final rendering on both desktop and mobile devices.
One can use Free PageSpeed Insights Checker to identify and address problems that are slowing down the web application. Lab data from the Chrome User Experience Report dataset is integrated with real-world data using an open-source application called Lighthouse for collection and analysis. The outcome is a performance score along with a list of suggestions. It reports on how well a website is used on desktop and mobile devices and offers recommendations for how to make the page better.
The best PageSpeed Insights checker examines speed from a single user experience and may have some aggregate data, but it shouldn't be the only tool for performance testing. For instance, PageSpeed Insights does not demonstrate the performance of a web application under normal or abnormally high load.
