Google announces page experience ranking rolling to Search in 2021 and defines the exact signals used: Core Web Vitals (LCP, FID, CLS) with thresholds like LCP < 2.5s, FID < 100ms, CLS < 0.1, plus HTTPS and Safe Browsing. Search Console adds a page experience report and Performance filter. Signed exchanges prefetching yields a reported LCP improvement of 300 milliseconds (~20%) and 12% more engagement. AMP offers an optimizer and an AMP page experience guide for actionable fixes.
