Free Heading Structure Checker
Analyze your page's heading hierarchy for SEO best practices. Detects missing H1 tags, multiple H1s, skipped heading levels, empty headings, and provides an overall SEO heading score.
What This Tool Checks
- Missing H1 - Every page needs exactly one H1 tag
- Multiple H1s - Only one H1 should exist per page
- Skipped Levels - Going from H1 to H3 without H2 hurts accessibility
- Empty Headings - Headings without text waste SEO potential
- Heading Order - H1 should be the first heading on the page
