What is this heading outline extractor?
A free tool that extracts the H1–H6 heading outline of any page. Enter a URL and it fetches the page server-side, then reads every heading in document order in your browser and renders an indented outline — the page's de facto table of contents. It also flags the structural problems that hurt SEO and AEO: a missing H1, multiple H1s, and skipped levels such as H2 jumping to H4. The URL you enter is fetched by our server; only that URL is requested.
How to use it
- Paste the URL whose heading structure you want to check.
- Press “Extract outline” — the page is fetched server-side and its headings are parsed.
- Review the indented H1–H6 outline, the per-level counts, and any flagged issues.
Common use cases
- Auditing whether a page has exactly one H1 and a logical heading hierarchy.
- Finding skipped heading levels (H2 → H4) before they hurt accessibility and SEO.
- Structuring content for AEO so AI answer engines can quote the right section.
