PageSpeed Insights (PSI) measures the performance of a page on both mobile and desktop devices and provides suggestions on how to improve it. PSI measures three key performance metrics: First Contentful Paint (FCP), Largest Contentful Paint (LCP), and Cumulative Layout Shift (CLS). FCP is the time it takes for the first element of content to appear on the screen; LCP is the time it takes for the largest element of content to appear; and CLS measures visual stability by assessing if elements shift around unexpectedly while loading. Using these metrics, PSI generates an overall score between 0-100, with higher numbers indicating better performance.
Using data from Chrome User Experience Report, PSI analyzes URLs submitted by users and generates reports with recommendations on how to improve their pages’ speed and user experience. The report begins with an overview of the URL’s performance against all metrics mentioned above plus any additional metrics it may have identified as problematic for that particular URL. Then, it presents more detailed information about each metric such as frequency distributions, field data from real-world Chrome users, and optimization opportunities based on experience from millions of websites across the web. Finally, PSI provides specific recommendations to improve page speed in areas like caching policy or JavaScript execution time.
Using PSI is fairly simple; all you need to do is enter your webpage’s URL into the search bar on the PSI homepage and press enter. After a few seconds (or minutes depending on how many elements your webpage contains), PSI will generate a report with detailed insights into your webpage’s performance as well as suggestions for improving it. If you are not tech-savvy enough to implement these changes yourself, there are plenty of services available online that can help you get your webpages up to speed.
PageSpeed Insights is a powerful tool that can help website owners optimize their page speed effectively and efficiently. By providing detailed data on page performance along with specific recommendations for improvement, PSI is invaluable in making sure that your website loads quickly without sacrificing quality or reliability.
