Headings Checker
Paste HTML or a public URL to extract and analyse the heading structure (H1–H6). Identifies missing H1 tags, duplicate H1s, skipped heading levels, and heading hierarchy issues that can affect SEO and accessibility.
Analyse your heading structure
Checks H1–H6 hierarchy, detects skipped levels and multiple H1s, maps keyword distribution across headings, and scores overall structure — with fix suggestions.
Features

- Flags missing H1, duplicate H1, and skipped levels
- Shows heading hierarchy as a visual outline
- Counts headings per level
- Checks keyword presence in headings (optional)
- Browser-only HTML analysis
How to use it
