H1 Checker
Scan any URL to check for missing or multiple H1 tags, weak or unclear headings, and heading-structure issues that hurt both search rankings and AI readability.
How it works
Enter a page URL to scan the live page, or switch modes and paste a draft H1 to check the wording on its own.
Optionally add a target keyword or topic so the tool can check whether your H1 covers it.
Submit to get a scored report: missing or duplicate H1 tags, heading length and clarity, and heading-structure issues.
Review the AI-suggested H1s at the bottom — each has a copy button so you can drop one straight into your CMS.
Frequently asked questions
How many H1 tags should a page have?
One. A single H1 that states what the page is about gives search engines and AI assistants an unambiguous main topic. Multiple H1s dilute that signal, and a missing H1 leaves crawlers guessing — the checker flags both.
What makes an H1 “weak”?
Vague or generic wording — headings like “Welcome” or “Home” describe nothing. A strong H1 names the page’s actual subject, ideally including the topic people search for, in natural language.
Why does the scan miss headings I can see on the page?
The tool reads the HTML your server returns. If your headings are injected by JavaScript after load, they won’t appear in the scan — and some crawlers and AI bots will miss them the same way.
Is there a usage limit?
Yes — the suggestions are AI-generated, so runs are limited to a few per minute per visitor. If you hit the limit, wait a moment and try again.
Do H1s matter for AI search too?
Yes. AI assistants that summarize or cite pages lean heavily on heading structure to understand content. A clear H1 plus descriptive H2s makes your page far easier to represent accurately in AI answers.
