One H1, clean nesting
Search engines and screen readers use headings as the page outline. One H1, then H2s under it, then H3s — never jumping a level.

Heading Structure Checker
Paste your HTML and see the full H1–H6 outline, whether there's exactly one H1, and whether any heading levels are skipped.
What this tool checks
Why skipped levels hurt
Jumping H2 → H4 breaks the document outline, confusing assistive tech and weakening the topical structure crawlers rely on.

FAQ
Common questions
Does Arabic RTL change anything? +
No — heading levels are structural, not visual. The check works the same for Arabic and English content.
Is more than one H1 always wrong? +
HTML5 technically allows it, but for SEO clarity one H1 that states the page topic is the safest, clearest choice.
