Heading Structure Checker

Audit the nested structure of headings (H1-H6) to check for hierarchy violations.

How to Use Heading Structure Checker

  1. 1. Enter the website URL to scan, or paste the page source code.
  2. 2. Run the "Analyze Heading Structure" command.
  3. 3. Observe the collapsible nested tree of H1-H6 tags, highlighting any skipped hierarchy steps in red warnings.

About Heading Structure Checker

Headings establish the structural outline of a webpage. They should flow in a logical, nested hierarchy (e.g. H1 followed by H2, then H3 nested within H2). Skipping heading levels (like jumping from an H2 directly to an H4) makes it harder for screen readers and search crawlers to map your page's logic. This auditor scans and visualizes your heading structure.
