What this checks
Lists every heading on the page from H1 to H6 and checks the hierarchy: exactly one H1, the first heading is an H1, no skipped levels (for example H2 straight to H4), and no empty headings.
It's one of the 35 checks in the free AI Visibility Checker, which scores a page on everything AI engines look at.
Heading Structure Analyzer FAQs
How many H1s should a page have?
One. A single H1 states the page's main topic; H2s and H3s break it into sections and subsections.
What is a skipped heading level?
Jumping more than one level down, for example from an H2 straight to an H4. It breaks the outline that crawlers and screen readers rely on.
Why do headings matter for AI search?
AI engines use headings to split a page into sections and pull answers from them. A clean hierarchy makes your content easier to extract and cite accurately.
Do headings have to be visible?
Yes. Headings should be real, visible section titles, not hidden text or styling hacks.
