Page Speed Checker

Free Page Speed Checker — Google PageSpeed Insights Test

Page speed is a direct Google ranking factor. Slow pages rank lower, have higher bounce rates, and convert fewer visitors into customers. This free Page Speed Checker uses the Google PageSpeed Insights API to test any URL and return performance scores, Core Web Vitals measurements, and specific optimization recommendations for both mobile and desktop.

Enter any URL to get an instant performance audit. The tool returns your overall performance score (0–100), individual Core Web Vitals metrics, opportunities for improvement, and diagnostics identifying specific issues. Use it to benchmark your site, identify bottlenecks, and track improvements after optimization work.

Google PageSpeed data comes directly from the Chrome User Experience Report (CrUX), which is based on real user data from Chrome browsers worldwide, making it one of the most accurate measures of real-world page performance.

Understanding Your PageSpeed Score

The PageSpeed score is a weighted average of several lab metrics, each measuring a different aspect of loading performance. A score of 90 or above is Good (green), 50–89 Needs Improvement (orange), and below 50 is Poor (red).

LCP (Largest Contentful Paint). Measures how long it takes for the largest visible element on the page to load. Target: under 2.5 seconds. Poor: over 4.0 seconds.

CLS (Cumulative Layout Shift). Measures visual stability — how much page elements shift as the page loads. Target: under 0.1. Poor: over 0.25.

INP (Interaction to Next Paint). Measures responsiveness to user interactions. Target: under 200ms. Poor: over 500ms.

FCP (First Contentful Paint). Time until the first piece of content is rendered. Target: under 1.8 seconds.

How to Improve Page Speed

Compress images. Images are the most common cause of slow page loads. Use WebP format, compress images before upload, and add lazy loading to images below the fold.

Enable browser caching. Set cache-control headers so returning visitors load assets from their local cache instead of downloading them again.

Minify CSS, JavaScript, and HTML. Remove whitespace, comments, and redundant code from your files. Use our CSS Minifier to reduce stylesheet size.

Enable compression. Use Gzip or Brotli compression on your server to reduce the size of HTML, CSS, and JS files transferred over the network.

Use a CDN. A Content Delivery Network serves static assets from servers geographically close to each visitor, reducing network latency significantly.

Eliminate render-blocking resources. Scripts and stylesheets in the page head block rendering. Defer non-critical JavaScript and move scripts to the end of the body.
