What is Core Web Vitals?

Core Web Vitals are Google's three user-experience metrics: Largest Contentful Paint (LCP, loading), Interaction to Next Paint (INP, responsiveness), and Cumulative Layout Shift (CLS, visual stability).

Also known as: CWV · LCP INP CLS

Why it matters

They quantify real-world page experience, are a confirmed Google ranking signal, and directly affect bounce and conversion. Slow, unstable pages lose both rankings and customers.

Who needs it

Any site owner, but especially content-heavy, media-rich, or e-commerce sites where load time and layout stability materially affect revenue.

When it's used

Monitor continuously, and prioritize fixes when field data (from the Chrome UX Report or GSC) shows pages failing the 'good' thresholds.
