LCP (Largest Contentful Paint)

SEOWeight 2.5% (This check's share of the SEO score)Score 100

What this is

How long it takes for the main image or largest block of text to appear after the page opens (Largest Contentful Paint, LCP), measured in a single simulated mobile test.

Why it matters

It's one of Google's core page experience metrics. When the main content shows up slowly, visitors leave, and Google factors it into rankings.

What counts as passing

2.5 seconds or less passes; 2.5–4 seconds is a partial pass; over 4 seconds fails; not scored when no speed data was collected.
