On-Page SEO

H1 Checker

Check the H1 tag on any webpage instantly. Verify it exists, see exactly what it says, and confirm it's optimised for your target keyword.

What you need to know

One H1 per page — Each page should have exactly one H1 tag. Multiple H1s confuse Googlebot about the page's primary topic. Zero H1s waste a key ranking signal.

H1 ≠ page title — Your H1 is the visible heading on the page. Your title tag is what appears in Google search results. They can differ — and often should for different audiences.

Keyword in the H1 — Your primary target keyword should appear in the H1 — ideally near the start. This is one of the clearest on-page relevance signals you can send Google.

H1 length matters less than clarity — Unlike title tags, there's no strict character limit for H1s. Write for readers first — clear, specific, and descriptive beats keyword-stuffed every time.

Frequently asked questions

What is an H1 tag?

An H1 is the main heading of a webpage, defined with the <h1> HTML tag. It's typically the largest text on the page and signals to Google what the page is about.

Does the H1 affect SEO rankings?

Yes. The H1 is one of the most important on-page SEO signals. Including your target keyword in the H1 is a standard best practice for ranking.

Should my H1 match my title tag?

They don't need to match exactly, but they should be consistent. Your title tag is optimised for search results clicks; your H1 is optimised for page visitors.

What if my page has no H1?

Fix it. A missing H1 means Google has to guess your page topic from context. Add a clear, keyword-relevant H1 and you'll see an improvement in how the page is understood.
