What is PageSpeed Insights?

PageSpeed Insights is a web performance evaluation tool developed by Google. It analyzes the content of a web page, then generates suggestions to make that page faster. It provides a score for both mobile and desktop versions of a site, and offers specific recommendations for improvements related to aspects like optimizing images, leveraging browser caching, minifying CSS and JavaScript, and improving server response time. It is used by web developers and site owners to identify and address performance bottlenecks, ultimately aiming to improve user experience and SEO.
