Free H1 and heading structure checker
Headings are the outline machines read first. One clear H1 stating the page's topic, followed by a logical H2/H3 hierarchy, is how search engines and AI answer engines segment your page into quotable passages. This tool checks your H1 count, heading order, and whether the page uses semantic HTML landmarks.
How to fix what it finds
- Exactly one H1 per page, stating the page's topic in the words searchers use.
- Do not skip levels (H2 to H4): hierarchy is meaning, not styling.
- Phrase section headings as the questions people ask; AI engines match questions to passages.
- Put a direct answer in the first sentence under each question-shaped heading.
Frequently asked questions
Does having multiple H1s hurt SEO?+
Google says it can handle multiple H1s, but one clear H1 removes ambiguity for every system reading your page, including AI engines deciding what the page is about. There is no upside to two.
Do headings matter for AI search?+
Yes, arguably more than for classic search: engines lift passages, and a question-shaped heading with a direct answer under it is the easiest passage to lift and cite.
