Questions
Why do headings matter for AI answers?
Answer engines chunk pages by heading. A clear H2 that matches the question makes the paragraph under it easy to lift as an answer.
Does the tool run JavaScript?
No. It reads the HTML the server returns. Headings injected by client-side scripts won't appear.
