Core Web Vitals measure important parts of loading, interaction responsiveness and visual stability using LCP, INP and CLS.
What the metrics mean
Largest Contentful Paint measures when the main visible content becomes available. Interaction to Next Paint measures responsiveness after a user action. Cumulative Layout Shift measures unexpected movement. Field data reflects real visitors; laboratory tests help diagnose causes.
Why they matter
Performance shapes user patience and conversion, particularly on mobile. Core Web Vitals are also part of Google’s page-experience systems, but a fast irrelevant page will not outrank a slower page solely because of speed.
Common improvements
Optimize the actual hero asset, reserve image dimensions, reduce blocking CSS and JavaScript, simplify third-party scripts, cache static resources and avoid loading heavy widgets before they are needed.
How to measure
Use Search Console for grouped field issues, PageSpeed Insights for field and lab context, and browser performance tools for diagnosis. Test several templates—not only the homepage.
