What the H1 Checker does
Headings are the skeleton search engines and screen readers navigate by, and they break silently — themes render duplicate H1s, page builders skip levels, and nobody notices for years. This checker renders your heading structure as a visual tree, flags structural issues (missing H1, multiple H1s, skipped levels), checks focus-keyword targeting, and audits up to 200 URLs in one run.
The competitor comparison earns its place: seeing the H1s of the pages that outrank you for a term shows the intent-framing that wins — often the difference is "Best X for Y" versus your generic "X Guide". The AI rewrite suggestions give you starting points that respect both keyword and readability. For titles rather than headings, the same treatment lives in the Title Length Checker.
How to use it
- Enter a URL — or up to 200 for a site-wide heading audit.
- Read the visual heading tree and fix structural flags: one H1, no skipped levels.
- Compare your H1 against top-ranking competitors for your focus keyword.
- Apply or adapt the AI rewrite suggestions where your H1 misses keyword or intent.
H1 Checker FAQ
Does a page really need exactly one H1?
One is the convention worth keeping. HTML5 technically permits more; in practice one clear H1 stating the page topic serves accessibility, is unambiguous for crawlers, and forces you to decide what the page is actually about.
Should the H1 match the title tag?
Closely related, not necessarily identical. The title tag is written for the SERP (click-worthy, pixel-limited); the H1 confirms on arrival that the click was correct. Same core keyword and promise, freely different phrasing.
Why does heading hierarchy matter beyond the H1?
Skipped levels (H2 jumping to H4) break document structure for screen readers and muddy how crawlers relate sections. Clean hierarchy also feeds featured snippets and AI-generated answers, which frequently lift heading-plus-paragraph blocks verbatim.
