## Definition

Core Web Vitals are Google's set of user experience metrics — Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS) — used as ranking signals in Google Search. They measure loading speed, interactivity, and visual stability.

## Why It Matters for AI Search

Core Web Vitals affect AI citation indirectly through their impact on traditional search rankings and crawl efficiency. Pages that load slowly or have poor user experience generate negative behavioral signals that can depress overall page authority — including the authority that contributes to AI retrieval preference. For brands building content at scale, maintaining strong Core Web Vitals on high-priority pages protects the technical health that underpins AI citation authority.
