Test your website performance, Core Web Vitals, and get actionable optimization recommendations
Website speed is a critical factor for user experience and search engine rankings. Google uses Core Web Vitals as ranking signals, making performance optimization essential for SEO success.
This tool analyzes your website's performance, measures Core Web Vitals, and provides specific recommendations to improve loading speed and user experience.
Enter a publicly accessible URL. The test will analyze performance on both mobile and desktop devices.
Focus on LCP (loading performance), FID (interactivity), and CLS (visual stability). These are Google's official user experience metrics and directly impact SEO rankings.
Use modern formats like WebP or AVIF, implement responsive images with srcset, compress images without visible quality loss, and lazy load below-the-fold images.
Use browser caching, CDN caching, and service workers for offline capabilities. Set appropriate cache headers for static assets (1 year) and dynamic content (shorter periods).
Minify CSS, JavaScript, and HTML. Enable Gzip or Brotli compression on your server. Remove unused code and consider code splitting for larger applications.
Audit third-party scripts (analytics, ads, social widgets). Load non-critical third-party code asynchronously or defer loading until after the main content.
Serve static assets from a CDN to reduce latency. Choose a CDN with edge locations close to your target audience for faster delivery.
Set up performance monitoring with tools like Google Search Console, Lighthouse CI, and real user monitoring (RUM) to catch regressions early.
