Overview

Run Google PageSpeed Insights on a list of URLs or an entire sitemap to get Core Web Vitals, performance scores, and detailed audits for both mobile and desktop. Pinpoint exact issues slowing down your site.

Website performance is non-negotiable for good SEO and a positive user experience. Manually checking every page with Google's PageSpeed Insights tool is a slow, repetitive process that doesn't scale. This tool automates the entire workflow, letting you analyze a list of individual URLs or an entire website in one go. ### Full-Site Performance Audits Provide a single URL and select the option to analyze the whole site from its sitemap. The tool will discover and test all the pages listed in your sitemap, up to your specified maximum, giving you a comprehensive overview of your site's health. This is ideal for initial client audits, pre- and post-launch benchmarking, or regular performance monitoring. ### Key Data Points You get the same critical data provided by Google's own tool, ready for bulk analysis. This includes: * **Overall Lighthouse Performance Score:** A single number (0-100) summarizing the page's performance. * **Core Web Vitals:** The real-world user experience metrics Google uses for ranking, including Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and Interaction to Next Paint (INP). * **CrUX Report Data:** Access field data from the Chrome User Experience Report, showing how actual users experience your page. * **Mobile & Desktop Analysis:** Choose to run tests simulating either a mobile or desktop device to see how performance differs. For deep technical analysis, you can enable a detailed report which provides granular data on every single audit performed by Lighthouse. This helps developers identify the specific scripts, images, or code slowing things down.
