Why headings matter
Headings are the page's table of contents
Readers scan headings to decide whether a page answers their question, and search engines and AI systems use them to understand how a page is organised. A clear outline helps a section get picked for a featured snippet or quoted in an AI answer.
- One H1 that says what the page is about, close to the title tag.
- H2s for the main questions the page answers, H3s for the details under each.
- No skipped levels just for styling: use CSS for size, headings for structure.
- No empty or decorative headings, which add noise for screen readers and crawlers.
Multiple H1s aren't an error to Google, which handles them fine. One clear H1 is still the cleanest structure for readers and accessibility tools.
FAQ
Heading checker FAQ
How many H1 tags should a page have?
One is the usual best practice. Google says multiple H1s won't cause problems, but a single clear H1 is easiest for readers and assistive tools.
Is it bad to skip heading levels?
Going from H2 straight to H4 won't hurt rankings directly, but it makes the outline harder to follow for screen readers. Use headings in order.
Does the checker see headings added by JavaScript?
No. It reads the HTML the server sends. If your headings only appear after scripts run, check that they're in the rendered page Google sees.
Is the heading checker free?
Yes. No login or DataForSEO account is needed.
