Open any article and the biggest heading at the top is almost always the H1. In HTML it’s the <h1> element, the top level of the page’s header tags. Visitors read it to confirm they’ve landed in the right place. Search engines read it as a strong summary of the page’s main topic.
<h1>Emergency Dentist in Austin: Same-Day Appointments</h1>H1 versus title tag
They’re easy to confuse because they often say similar things:
| Title tag | H1 | |
|---|---|---|
| Where it appears | Search results, browser tab | On the page itself |
| Who it’s written for | Searchers choosing a result | Visitors who’ve already arrived |
| Typical length | 50-60 characters | Whatever reads naturally |
They don’t have to match word for word. The title tag for Brightside Dental’s emergency page might be “Emergency Dentist Austin, TX | Same-Day | Brightside Dental”, while the H1 drops the brand and reads more naturally. But they should clearly describe the same thing. A big mismatch is one reason Google rewrites titles.
Can a page have more than one H1?
Technically yes. HTML allows it, and Google has said multiple H1s won’t cause a problem for ranking. In practice, one H1 per page is still the clearer choice. It gives screen reader users one obvious main heading, keeps the outline tidy, and avoids the common theme bug where the logo or site name is wrapped in an H1 on every page.
Writing a good H1
- Describe the page’s main topic in plain words, including the main keyword where it fits naturally.
- Make it specific. “Our Services” says little; “Drain Cleaning and Sewer Line Repair” says a lot.
- Keep it near the top of the content, not below a large slider.
- Make it unique across the site.
Common mistakes
- No H1 at all, often because a page builder styles a paragraph to look like a heading.
- The logo in an H1 on every page, so every page shares the same main heading.
- Hiding the H1 with CSS, or putting it in an image with no text.
- Using H1 for styling, for example to make a sidebar line big.
How to check
Right-click a page, choose Inspect, and search the HTML for <h1. RankThat’s Site Audit flags pages with a missing H1, more than one H1, and headings that skip levels, which covers the usual problems across a whole site. Getting headings right is part of basic on-page SEO.
