Understanding Core Web Vitals
Core Web Vitals are Google's metrics for measuring user experience. Largest Contentful Paint (LCP) measures loading performance and should be under 2.5 seconds. Cumulative Layout Shift (CLS) measures visual stability and should be under 0.1. Total Blocking Time (TBT) approximates interactivity and should be under 200ms. These metrics directly impact your Google search rankings.
