Core Web Vitals

Google's three measurements of real-world page experience: loading, interactivity and visual stability.

Largest Contentful Paint measures how long the main content takes to appear, Interaction to Next Paint measures how quickly the page responds when someone taps or clicks, and Cumulative Layout Shift measures how much the page jumps around while it loads.

They are a ranking signal, but a weak one, and this is routinely oversold. They act mostly as a tiebreaker between pages of comparable relevance. A slow page that answers the question still beats a fast page that does not.

Where they genuinely pay is conversion. INP in particular correlates with abandonment, and layout shift is the thing that makes someone tap the wrong button and leave.
