How Core Web Vitals Works

Core Web Vitals measures page behaviour through separate signals. Largest Contentful Paint examines when the main content appears. Interaction to Next Paint considers how promptly a page responds after an action, while Cumulative Layout Shift assesses unexpected movement during loading.

These signals come from real user experiences and controlled testing tools. Results can change between pages because images, scripts, fonts and hosting affect each page differently. Page Speed work may improve these results, but a faster loading time does not automatically mean that every interaction or layout remains stable.
