Page experience and Core Web Vitals
Short answer
Core Web Vitals are among the signals Google's ranking systems use, but there is no single page experience signal. Good thresholds are LCP within 2.5 s, INP under 200 ms and CLS under 0.1. Good scores don't guarantee top rankings, and relevance can outweigh a sub-par page experience.
