The Heading Tag Checker is a free SEO tool that extracts and analyzes the complete H1 through H6 heading structure of any web page. Proper heading hierarchy is one of the most fundamental on-page SEO signals. Search engines use headings to understand page structure and topic hierarchy. This tool fetches the page, extracts every heading tag in document order, and then checks for common issues: missing H1 tags, multiple H1s, skipped heading levels (like jumping from H1 to H3), empty headings, and overly long headings. The results are displayed as a color-coded visual tree that makes structural problems immediately obvious.
Paste any web page URL. The tool adds https:// automatically if you skip it.
The tool fetches the page server-side and extracts every H1-H6 heading tag in the order they appear in the HTML.
See the total heading count and breakdown by level. A well-structured page typically has 1 H1, several H2s, and H3s under each H2.
Errors (red) are critical problems like missing H1. Warnings (yellow) are best-practice violations. Notices (blue) are suggestions.
The indented color-coded tree shows the heading structure. Each level is indented further and color-coded so you can spot where the hierarchy breaks.
