What are Core Web Vitals?
Core Web Vitals are a set of performance metrics Google uses to measure real-world user experience on your pages. The three signals are Largest Contentful Paint (LCP, loading), Interaction to Next Paint (INP, interactivity) and Cumulative Layout Shift (CLS, visual stability).
Why Core Web Vitals matter
Core Web Vitals are ranking factors and part of the page experience signal. Slow, jumpy pages frustrate users and get outranked by faster competitors. The metrics are measured from real user data via Chrome, so they reflect actual visitor experience.
Target values and fixes
- LCP under 2.5 seconds — optimize images, reduce server response time.
- INP under 200 ms — minimize JavaScript blocking interactions.
- CLS under 0.1 — reserve space for images and ads.
