Core Web Vitals

Google's set of three page experience metrics — LCP, CLS, and INP — used as a ranking signal in Search.

Core Web Vitals are Google's standardized set of three user-experience metrics that measure loading performance (Largest Contentful Paint), visual stability (Cumulative Layout Shift), and interactivity (Interaction to Next Paint). They function as a tie-breaker ranking signal in Google Search, requiring 75% of a page's users to meet all three 'good' thresholds simultaneously.
