What We Found
Analyze H1 Headings on Any Page
The H1 is the most important heading on a page โ search engines expect exactly one, and it should describe the page's topic. Enter any URL and this free checker fetches the page and extracts every H1 it finds.
See each heading's text and length, plus a verdict on common issues: missing H1s, multiple H1s, and headings that are too long or empty.
Every H1 extracted
The full list of H1 tags is pulled from the page's HTML โ none hidden, none guessed.
SEO verdicts
Each result flags issues like missing, duplicate, or overlong H1s so you know what to fix.
How it works
Submit a URL and our server fetches the page, parses its headings, and analyzes each H1. The check runs server-side against any public URL.
How to use
- Enter the URL you want to analyze.
- Click the check button.
- Review every H1 found and fix any flagged issues.
Frequently Asked Questions
Why does a page need an H1 tag?
The H1 tells search engines and readers what the page is about โ pages with a clear, single H1 tend to perform better in search.
Can a page have more than one H1?
Technically yes in HTML5, but SEO best practice is one H1 per page with a clear topic, supported by H2s and H3s for structure.
How long should an H1 be?
Aim for a concise, descriptive heading โ roughly under 60 characters โ that includes the page's main topic.
What if a page has no H1?
The checker flags it as missing so you can add one; it's one of the most common on-page issues.
Is the checker free?
Yes, free with no signup.
