H Tag / Heading Checker
Enter any URL to inspect its heading structure. Detects missing H1s, skipped levels, and empty tags that confuse search engines and screen readers.
Why heading structure matters for SEO
Search engines use heading tags (H1 through H6) to understand the topic hierarchy of a page. A single, descriptive H1 tells crawlers what the page is about. Sequential subheadings (H2, H3…) help AI answer engines extract structured answers from your content. Skipping levels or using multiple H1s weakens this signal.
What this tool checks
- Presence and count of H1 tags
- Sequential heading hierarchy (no skipped levels)
