# Heading Structure Extractor

> Agent-friendly Markdown of https://www.buildseo.org/free-tools/heading-structure-extractor — full index for AI agents: https://www.buildseo.org/llms.txt

Extract a page's h1-h6 outline and catch skipped levels and duplicate H1s.

## How it works

Enter a URL and the extractor fetches the page and pulls every h1-h6 into an ordered outline — the same document structure screen readers and search engines use to understand the page.

It flags the classic problems: no H1, more than one H1, skipped levels like h2 jumping to h4, and empty heading tags.

The outline and findings download as CSV or JSON, free and instant.

## Frequently asked questions

### Why do skipped heading levels matter?
Assistive technology and outline parsers treat headings as a tree. Jumping from h2 to h4 breaks the tree — content lands under the wrong parent and scanning gets harder.

### Is one H1 per page still the rule?
It remains the safest convention. Search engines cope with multiple H1s, but a single clear H1 states the page's topic unambiguously for every consumer, human or agent.

## Structure readable. Now build the authority behind it.
