Proper HTML heading structure (H1–H6) is critical for both SEO and accessibility. Search engines rely on clear heading hierarchies to understand the content of each page, while screen readers use them to guide users through your site. A well-structured heading setup improves discoverability, readability, and user experience across the board.
With our free tool, you simply enter your domain, and we automatically crawl every subpage to analyze its heading structure. The scanner checks if each page follows best practices - from ensuring only one H1 per page to maintaining a logical H2–H6 order - and highlights any issues that could impact SEO or accessibility.

How to use it
1. Enter your domain (e.g., https://example.com) in the scanner.
2. We crawl your site and analyze the heading structure of every subpage.
3. Get a detailed report showing correct usage and potential issues.
4. Fix the flagged headings in your CMS or code to improve SEO and accessibility.
5. Re-run the scan after updates to validate improvements.

✅ That’s it - with a clean heading hierarchy, your site is easier to read, better for accessibility, and more search-engine friendly.
