About What To Fix First
What to Fix First is a free, no-signup web tool that analyzes any URL's Core Web Vitals (LCP, CLS, INP), identifies the single highest-impact fix, and projects time savings and estimated conversion recovery. It shows lab and (when available) field data, breaks down where load time is spent (server, discovery, download, render), and links to actionable guides for common fixes like image optimization. Conversion impact is modelled using ~2% conversion improvement per second recovered (capped at 20%).
