Heading Structure Analyzer

One H1, then never skip a level

The H1 is the page title and there should be exactly one. After that, an H3 must sit inside an H2, never directly under the H1. Skipped levels do not break ranking, but they break the outline that assistive technology and featured snippets use to understand the page.

Headings are scanned, not read

Most readers see only the headings as they scroll. If the headings alone do not tell the story, the structure is wrong. A useful test: read the H2s in order — they should work as a summary of the article.

Length and keywords

Past about 70 characters a heading wraps in most sidebars and search results. The target phrase belongs in the H1 and one or two H2s, not in every heading — repetition reads as stuffing and adds nothing a crawler needs.

Where to go next

If the structure needs rebuilding, Blog Outline Builder generates the H2s. For sentence-level readability, try the Readability Checker.

How to use Heading Structure Analyzer
