Performance & Heuristics
Analyze page load performance and technical SEO heuristics. Get TTFB, page size, render-blocking resources, and actionable severity-rated recommendations.
Why Performance Matters for SEO
Page speed is a confirmed Google ranking factor. Core Web Vitals — including TTFB, LCP, and CLS — directly affect where your pages appear in search results. Fast, well-optimized pages also improve user experience and conversion rates.
Metrics analyzed:
- Time to First Byte (TTFB) — server responsiveness
- Page weight (total transfer size)
- Render-blocking CSS and JavaScript count
- Lazy loading coverage for images
- Compression (Brotli/gzip) and HTTPS status
