What Is Largest Contentful Paint?
Largest contentful paint, or LCP, is a Core Web Vitals metric that records when the largest content element in the viewport becomes visible. That element is often a hero image, video poster, or large text block. It approximates the point at which the page main content has loaded for the user.
Why it matters
LCP is a key signal of perceived load speed and is used in search ranking and performance budgets. Tracking it in CI helps catch slow hero assets before they reach users.
