FAQ

Why does heading hierarchy matter for SEO?

Search engines and AI systems use heading hierarchy (H1 → H2 → H3) to understand content structure and importance. Skipped levels or multiple H1s can confuse crawlers and weaken topical signals.

Should H2 headings be questions?

Question-format H2s significantly improve featured-snippet eligibility and AI citation probability, since AI engines quote direct question-answer pairs.
