How to use this tool
Paste HTML markup rather than a page address. Extraction uses the document repaired by the browser’s HTML parser, so malformed source nesting may not appear exactly as originally written.
Results and examples
<h1>Introduction</h1><h2>Instructions</h2> yields those two headings in order. The H1 count is an editing clue, not a standalone measure of search quality or accessibility.
Limitations
- It does not fetch external pages or execute scripts that later create headings.
- An outline is neither complete HTML validation nor an SEO score.
