Heading Structure Analyzer

Screen-reader users navigate by headings. Skipped levels, empty headings, or multiple H1s break that navigation. Paste any URL and we'll show you the page's heading outline plus any structural issues.

Why heading structure matters

About 71% of screen-reader users navigate via headings (WebAIM survey). When headings skip levels or are missing, your content becomes opaque to assistive tech. WCAG 2.1 covers this under 1.3.1 Info and Relationships (Level A) and 2.4.6 Headings and Labels (Level AA).

What this tool checks

Exactly one <h1> per page
No skipped levels (H1 → H3 with no H2)
No empty headings
