Frequently Asked Questions
Only H1 and H2 — it counts lines starting with '# ' as H1 and '## ' as H2. It does not currently detect H3 through H6.
No — paste your content formatted as markdown headings (# for H1, ## for H2); it doesn't fetch or parse HTML from a URL.
Best practice is one clear H1 per page (your main topic statement) — zero H1s or multiple competing H1s can dilute the page's topical signal for search engines.
No — it only reports the H1 and H2 counts, not the sequence or nesting logic between them.
