EqualWeb – Heading Structure Tester

About

EqualWeb Heading Structure Tester is an essential accessibility tool that helps developers, designers, and content creators ensure their heading structure follows WCAG 2.2 guidelines.

Why Heading Structure Matters
Screen reader users rely on proper heading hierarchy to navigate web pages efficiently. Skipped heading levels or missing H1 tags create confusion and make content difficult to access for users with visual impairments.

Key Features
Visual Heading Tree See your page's complete heading structure displayed as an interactive tree. Each heading is shown with its level (H1-H6), text content, and position in the document hierarchy.

Issue Detection The tool automatically identifies common heading structure problems:

Missing H1 heading
Skipped heading levels (e.g., H2 to H4)
Multiple H1 headings
Empty headings
Headings used for styling rather than structure
