Above the fold is the part of a page a visitor sees before scrolling. For SEO and conversions, you want meaningful content, your main heading, a clear intro, and primary value, to appear there rather than below a tall hero, a cookie banner, or stacked ads. Google's page experience signals and users alike reward pages that deliver substance early.

This tool inspects the raw HTML and measures how early key content appears in the document source: where the H1 sits, how soon body text begins, and how much markup precedes it. It cannot pixel-measure your exact layout, but it reliably flags pages that bury their first heading or paragraph behind large amounts of head markup, scripts, and structural code.

An H1 that appears very late in the HTML often means the real content is pushed down by heavy navigation, banners, or framework markup. Crawlers and AI search engines read the source top to bottom, so content that appears early is more likely to be treated as the page's main subject. An early, clear H1 helps both ranking and snippet selection.

Less is better. Ideally your H1 and first paragraph appear within the first portion of the body, after only essential header markup. This tool reports how many characters of HTML precede your first heading and first real paragraph so you can spot pages where thousands of characters of markup load before any visible content.

No. Lighthouse measures rendered, visual metrics like Largest Contentful Paint. This tool is a fast, source-level heuristic that complements those. It answers a different question, 'is meaningful content present early in the HTML?', which affects crawlability and AI readability, not just visual paint timing.

Move your main heading and intro copy higher in the HTML, defer non-critical scripts, and avoid placing large inline scripts or oversized hero markup before your content. If content is injected by JavaScript after load, render the critical part server-side so it appears in the raw HTML where crawlers can read it immediately.

Yes. Google indexes the full page, including content below the fold and content revealed by scrolling. The advantage of leading with content is emphasis and clarity: early content signals the page's topic, improves snippet selection, and gives users immediate value, which lifts engagement and reduces bounces.
