Clear structure helps Google, AI and readers

Headings are your page's table of contents: they tell search engines, AI assistants and screen readers what each section is about. A clean hierarchy makes your content easier to understand and to quote in AI answers.

The tool extracts every heading from the HTML, shows them as a tree and flags the most common mistakes with advice on how to fix them.
