PageSpeed Insights analyzes a web page's performance and presents diagnostic recommendations. It combines available real-user performance data with a lab analysis, helping you understand where a website may feel slow or unstable.
Find performance problems
Inspect a public page to identify loading, responsiveness, or visual-stability issues that could affect how users experience your product.
Prioritize improvements
Use the reported diagnostics to choose specific changes worth investigating rather than optimize blindly. Mobile and desktop results can reveal different parts of the problem.
