PageSpeed Insights
PageSpeed Insights is a free web performance analysis tool developed by Google that evaluates the speed and user experience of web pages on both mobile and desktop devices. It provides actionable recommendations to optimize page load times, improve Core Web Vitals scores, and enhance overall site performance based on real-world data from the Chrome User Experience Report and lab simulations.
Developers should use PageSpeed Insights to identify and fix performance bottlenecks that impact user engagement, search engine rankings, and conversion rates, particularly for optimizing websites to meet Google's Core Web Vitals thresholds. It is essential for front-end developers, SEO specialists, and site owners working on performance-critical projects like e-commerce platforms, content-heavy sites, or Progressive Web Apps (PWAs) where fast loading is crucial.
