Quick Definition
A set of three metrics (LCP, INP, CLS) that Google uses to measure user experience and as ranking factors.
Full Explanation
Core Web Vitals are a set of three specific metrics that Google considers essential to delivering a great user experience on the web. As of 2024, they are: Largest Contentful Paint (LCP) for loading performance, Interaction to Next Paint (INP) for interactivity, and Cumulative Layout Shift (CLS) for visual stability. These metrics became Google ranking factors in June 2021 and are measured at the 75th percentile of real user experiences via Chrome User Experience Report (CrUX). Good scores are: LCP under 2.5s, INP under 200ms, and CLS under 0.1. Core Web Vitals are part of Google's broader page experience signals.
