Free Page Speed Checker

Enter a URL above to analyze its loading performance. The tool measures Core Web Vitals and key performance metrics, then provides actionable recommendations to improve speed. Results include both mobile and desktop scores.

Why page speed matters for SEO

Google uses Core Web Vitals as a ranking signal. Pages that load slowly lose visitors — 53% of mobile users abandon sites that take longer than 3 seconds to load. Beyond rankings, page speed directly impacts conversion rates, bounce rates, and user satisfaction. Every 100ms improvement in load time can increase conversions measurably.

Key metrics explained

• Largest Contentful Paint (LCP) — measures loading performance, should be under 2.5 seconds
• Interaction to Next Paint (INP) — measures interactivity, should be under 200 milliseconds
• Cumulative Layout Shift (CLS) — measures visual stability, should be under 0.1
• First Contentful Paint (FCP) — time until first content appears on screen
• Time to First Byte (TTFB) — server response time

Common speed fixes

The most impactful optimizations are compressing and properly sizing images, enabling text compression (gzip or Brotli), removing unused CSS and JavaScript, and leveraging browser caching. Lazy loading offscreen images and deferring non-critical scripts can dramatically improve perceived load times without changing your content.

Auditite continuously monitors page speed across your entire site, alerts you when Core Web Vitals regress, and can automatically optimize images and assets using AI agents.
