Core Web Vitals

Google's three key metrics for measuring page experience: LCP, INP, and CLS.

Core Web Vitals are a set of real-world performance metrics defined by Google that measure the user experience of a web page. The three metrics are: Largest Contentful Paint (LCP), which measures loading speed; Interaction to Next Paint (INP), which measures interactivity; and Cumulative Layout Shift (CLS), which measures visual stability. Google uses Core Web Vitals as a ranking signal.
