H1 Tag

The H1 is the top-level heading element, <h1>, that names what a page is about for the person reading it. It is not the same as the <title> shown in the browser tab and often in search results. Google lists headings such as the H1 among the sources it may use to build a title link.

What it is and where the boundary lies

The H1 is the visible headline of the page content. The title element sits in the page head and labels the tab and the result; the H1 sits in the body and opens the article. They often say nearly the same thing, and Google advises keeping the title, the H1 and the main visual title consistent. The H1 is not a magic ranking switch: the SEO starter guide gives no H1-specific rule.

How it differs from similar terms

Element	Where it appears	Main audience
H1	top of the page content	the reader on the page
Title tag	browser tab and search result	the searcher choosing a result
Meta description	snippet under the result	the searcher deciding to click
Other headings (H2–H6)	sections inside the content	the reader scanning the page

Why it matters

A clear H1 tells a visitor within a second that they are on the right page. For search, Google documents that heading elements such as the H1 are one of several sources for title links, so an H1 that matches the topic helps Google show a fitting title if it rewrites yours. It is also the heading screen reader users meet first.

What Google documents and what it does not

• Documented: headings help users navigate; the H1 can be a source for title links; the title, the H1 and the visual title should agree; there is no ideal number of headings; out-of-order headings do not matter for Google Search, though semantic order helps screen readers.
• Not documented: one H1 per page as a requirement, a length limit, or a rule that the H1 must contain the main keyword.

How to write a good H1

1. Name the subject of the page in the words a visitor would use.
2. Make it consistent with the title tag, but not necessarily identical: the title can carry the brand and a tighter wording.
3. Keep it readable as a headline, not a list of keywords (keyword stuffing).
4. Make it specific: one H1 for one topic, different from the H1 of other pages.
5. Put it in the HTML, visible on the page, not only in an image or a script.
6. Use H2–H6 below it to break the content into sections.

Practical example

Common mistakes

• Treating the H1 as a ranking lever: Google gives no such rule; write it for the reader.
• Stuffing keywords: an unreadable H1 helps neither visitor nor title-link generation.
• The same H1 on many pages: pages become hard to tell apart.
• Styling a paragraph to look like a heading: screen readers and crawlers see no heading.
• Mismatching the title and the H1: it can lead to a rewritten title link.

How to validate the result

View the page source or the rendered HTML in the URL Inspection tool and confirm the H1 is present. Search for the page and compare the title link with your title and H1. If Google shows something else, align the title, the H1 and the visual title, then check again after recrawling.

More questions

Can a page have more than one H1?

Google’s documentation sets no required number of headings. Use the structure that makes the page clearest.

Should the H1 equal the title tag?

It should be consistent, not necessarily identical.

Does the H1 have a length limit?

None is documented. Keep it short enough to read as a headline.

Next practical step

Pick ten pages with many impressions and low CTR and compare each title, H1 and visible headline. The playbook on title tags shows how to test one honest rewrite.
