Heading Structure Analyzer
Visualize your entire H1–H6 outline, fix duplicate headings, and keep both crawlers and screen readers happy.
Run your first inspection to visualize the exact H1–H6 outline for any URL.
Why heading hierarchy matters
Search engines and screen readers rely on a clear H1–H6 outline to understand your content. A single, descriptive H1 followed by logical H2/H3 sections boosts accessibility and keeps featured snippets on topic.
What this analyzer reveals
Paste any URL and we’ll output the exact heading order as rendered. Spot duplicate H1s, missing H2s, or sudden jumps (H2 → H4) before they confuse crawlers or assistive tech.
Hierarchy checkpoints
- Single H1 — One page, one H1 that summarizes the topic.
- Sequential levels — Move from H1 → H2 → H3 without skipping numbers.
- Section clarity — Each H2 introduces a new topic, H3 dives deeper.
Accessibility boosts
- Descriptive text — Avoid generic headings like “Section” or “Intro.”
- Keyword variation — Use related keywords in H2/H3 to reinforce intent.
- Anchor readiness — Clean headings make it easy to link to sections internally.

Definitely. A logical outline is foundational for WCAG success criteria around structure and navigation.
We show headings in document order, even if they’re visually hidden. Remove redundant or empty headings to stay compliant.
