# Core Web Vitals

Google's headline page-experience metrics: LCP, INP, CLS.

A standardized set of Real User Metrics (RUM) Google publishes via the Chrome User Experience Report (CrUX). Currently Largest Contentful Paint (loading), Interaction to Next Paint (responsiveness, replaced FID in 2024), and Cumulative Layout Shift (visual stability). A weak input to ranking but a strong input to user satisfaction.
