Heading Structure Checker

See a page’s heading outline and find missing H1s and skipped levels.

Ensure Web Accessibility with a Heading Structure Checker

When building accessible websites or preparing documents, organizing your content logically is essential. A heading structure checker allows you to review the hierarchy of your headings, from H1 down to H6, ensuring that screen readers and search engines can easily navigate your information. Proper heading tags create a clear outline for your readers and significantly improve your overall user experience and SEO performance.

Why Proper Heading Hierarchy Matters

Search engines and assistive technologies rely heavily on structured tags to understand the context of a page. Skipping heading levels, such as jumping straight from an H1 to an H4, can confuse users who navigate via screen readers. By using a reliable heading structure checker, you can identify these gaps immediately and fix them before publishing. Good hierarchy leads to better readability, cleaner code, and improved search engine rankings.
