Heading Structure Analyzer

About Heading Structure Analyzer

Headings are the skeleton of your page. Readers scan them to decide whether to stay, and search engines use them to understand what each section covers. A broken hierarchy - two H1s, a jump from H2 to H4, headings that ramble - quietly hurts both. The free Heading Structure Analyzer shows you the skeleton exactly as a crawler sees it.

Paste the HTML of a page, or just list your headings one per line with optional prefixes like "H2:" or "##". The tool builds an indented outline, counts headings per level, and flags the classic problems: missing or multiple H1s, skipped levels, and headings longer than 60 characters.

A healthy heading structure

• One H1: a single main title that matches the page topic and search intent.
• Logical order: H2 sections under the H1, H3 points under their H2, never skipping a level.
• Short and clear: headings under about 60 characters that tell scanners what the section delivers.
• Descriptive, not clever: include the words a searcher would use, without stuffing keywords.

Check the outline before publishing any long page. Fixing a skipped level now takes seconds; fixing it after the page is indexed is a rewrite.
