Test any website with Google PageSpeed Insights — Lighthouse scores, Core Web Vitals (LCP, FID, CLS), mobile vs desktop, plus basic load metrics.
A website speed test measures how fast a website loads and provides actionable performance data. This tool integrates Google PageSpeed Insights to give you Lighthouse scores for Performance, Accessibility, Best Practices, and SEO, plus Core Web Vitals measurements including LCP (Largest Contentful Paint), FID (First Input Delay), CLS (Cumulative Layout Shift), FCP, TTFB, and TBT. Toggle between mobile and desktop analysis to see how your page performs on different devices. Google uses these metrics as ranking signals, so optimizing them directly improves your search visibility.
