Flags missing or duplicate H1s

Confirms keyword placement

Verifies whether your target keyword actually appears in the H1, one of the clearest on-page relevance signals you can send Google.

Real H1 Checker example: before vs. after

A landing page's H1, before and after a quick fix.

Before · H1 missing

No <h1> tag found on the page

Google has to guess the page's main topic from context alone, a weak, avoidable relevance signal to lose.

After · H1 added

<h1>Project Management Software for Startups</h1>

One clear, keyword-relevant H1 gives Google an explicit signal about the page's primary topic.

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 primarily about.

Does the H1 tag affect SEO rankings?

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

Should my H1 match my title tag exactly?

They don't need to match exactly, but they should be consistent. Your title tag is optimized for search results clicks, your H1 is optimized for the page visitor already reading the content.

What if a page has more than one H1?

Multiple H1 tags on one page can confuse Google about which heading represents the page's primary topic. Keep exactly one H1 per page, and use H2/H3 for subheadings.

How do I fix a missing H1?

Add a single, clear, keyword-relevant <h1> tag near the top of the page content. It should describe what the page is about in plain language, not stuffed with keywords.
