FAQ
Frequently Asked Questions
Common questions about H1 tags and how to use this checker.
What is an H1 tag and why does it matter for SEO?
The H1 tag is the main heading on a webpage. It tells search engines and users what the page is about. Having a clear, descriptive H1 helps Google understand your page topic, which can positively influence your search rankings.
How many H1 tags should a page have?
SEO best practice is to have exactly one H1 tag per page. While Google can technically handle multiple H1s, having more than one can dilute the focus of your page and confuse search engines about the primary topic.
What happens if my page is missing an H1 tag?
A missing H1 is a missed SEO opportunity. Search engines may rely more on your title tag and meta description, but without an H1 the on-page structure is weaker. It can also affect accessibility for screen reader users.
Why does the tool use a Googlebot user agent?
Some websites serve different content to bots versus regular browsers. By using a Googlebot-compatible user agent, this tool fetches the same HTML that Google's crawler would see, giving you a more accurate picture of your page's SEO state.
Can I check any website, not just mine?
Yes. The tool works on any publicly accessible URL. You can audit competitor pages, client websites, or any public page to compare H1 tag strategies.
