Technical Definition
Core Web Vitals are Google's metrics measuring user experience: LCP (Largest Contentful Paint) measures loading performance, INP (Interaction to Next Paint) measures interactivity, and CLS (Cumulative Layout Shift) measures visual stability. They're confirmed ranking factors. Measured using field data (CrUX) from real Chrome users. Thresholds: LCP <2.5s, INP <200ms, CLS <0.1.
Simple Explanation (ELI13)
Core Web Vitals are Google's way of measuring if your website feels fast and smooth to use. There are three measurements: how quickly your main content loads (LCP), how fast buttons respond when clicked (INP), and whether stuff jumps around while loading (CLS). Good scores can help your rankings.
