Core Web Vitals

A set of specific metrics defined by Google to measure real-world user experience on websites. Core Web Vitals consist of three measurements: Largest Contentful Paint (LCP) which measures loading speed, First Input Delay (FID) which measures interactivity, and Cumulative Layout Shift (CLS) which measures visual stability. Google has used Core Web Vitals as a direct ranking factor since 2021. Websites that pass Core Web Vitals thresholds have a measurable advantage in Google search rankings over websites that fail these metrics.
