About this tool

Why heading hierarchy matters

Search engines and screen readers both treat heading levels as document structure. One H1 per page, no skipped levels (H2 → H4 is a no-no), nested H3s under their parent H2s. Bad hierarchy hurts accessibility AND makes Google's job of parsing your content harder.
