Core Web Vitals
Core Web Vitals are Google's set of three field metrics for measuring real-world user experience: Largest Contentful Paint (LCP) for loading, Interaction to Next Paint (INP) for responsiveness, and Cumulative Layout Shift (CLS) for visual stability. The good thresholds, measured at the 75th percentile of page loads, are LCP at or under 2.5 seconds, INP at or under 200 milliseconds, and CLS at or under 0.1. INP replaced First Input Delay as a Core Web Vital on March 12, 2024.
