Core Web Vitals
Sitecheck Team
A set of performance metrics (Largest Contentful Paint, Interaction to Next Paint, Cumulative Layout Shift) that measure user experience.
Core Web Vitals are standardized metrics from Google that focus on real-world user experience: LCP for loading, Interaction to Next Paint (INP) for interactivity, and CLS for visual stability.
Why it matters: These metrics are used in search ranking considerations and directly reflect how fast and stable your site feels to users.
Quick tips:
- Measure in-field (Real User Monitoring) and lab environments.
- Optimize images, font loading, and avoid synchronous scripts for better LCP.
- Minimize unexpected layout shifts to improve CLS.
