Accessibility review
Find empty elements or surprising jumps that deserve human inspection alongside the rendered page.
What it checks
Use the result as evidence, not a score.
- H1 through H6 elements in document order
- Visible heading text and empty heading elements
- H1 count
- Skipped heading-level transitions as review evidence
What it cannot check
- Whether headings accurately answer the visitor’s question
- Visual hierarchy created only through styling or client rendering
- Content quality, completeness, search intent, rankings, or AI citations
How it works
Input, inspect, improve, verify.
The tool processes what you enter, shows a plain-language result, and gives you a safer next step. Make the change on your website, deploy it, then test the live page again.

How to use the H1 tag checker
Enter a Public page URL or use Or paste HTML, then select Check heading structure. Pasted HTML takes precedence over the URL and is sent to the server for parsing. The result shows Headings found, H1 elements, Empty headings, and Skipped transitions, followed by the heading outline in source order.
For a live website check, leave the pasted HTML empty. This tool inspects the initial HTML response; it does not render JavaScript or certify accessibility. Use View example to inspect the Overhyped homepage and Clear to reset the inputs and result.
- Check the exact page or template you intend to edit.
- Compare the extracted outline with the rendered page.
- Use heading levels for document relationships, not only visual size.
Understand the result
Try an H1 and heading-level example
Paste <h1>Product guide</h1><h3>Setup</h3><h2></h2> into Or paste HTML. The checker reports three headings, one H1, one empty heading, and one skipped transition from H1 to H3. The outline retains the original order, so the jump remains easy to locate.
Review whether Setup is a direct section of Product guide. If it is, changing that H3 to H2 may express the intended relationship more clearly. Give the empty heading a useful label or remove it when it has no structural purpose. Check the edited HTML again.
- An H1 count is evidence, not a ranking score.
- A skipped level deserves structural review; it is not proof of a ranking penalty.
- Do not add keywords to headings merely to satisfy a checker.
Understand the result
When a website H1 checker differs from the browser
A large visible title may be styled text rather than an H1. Conversely, a heading in the initial HTML may be hidden or changed by scripts. The extracted text is not a visibility or assistive-technology test.
Inspect the rendered heading structure and keyboard or screen-reader navigation when accessibility is the goal. Review repeated page templates as well as individual articles, then deploy and recheck the live URL after making a change.
- This tool is a page-level check, not a whole-site crawl.
- Multiple H1 elements need context and a clear document hierarchy.
- Keep descriptive headings that reflect the content beneath them.

Pro tips
Small checks that prevent avoidable mistakes.
- Write headings for document structure and scanning before thinking about keywords.
- Keep the primary page topic clear without forcing every page into one rigid outline.
- Review the rendered accessibility tree when client-side code creates content after the initial HTML.
- Do not promote body text into headings merely to change its visual size.
Common issues and solutions
What to review when the result looks wrong.
Several H1 elements appear
Multiple H1 elements can be valid HTML. Confirm whether the resulting page hierarchy remains clear to users and assistive technology.
A level is skipped
Treat the jump as a review prompt rather than a severe SEO defect. Fix it when the document relationship is genuinely unclear.
The visible heading is missing
Inspect whether the label is styled text, generated only by JavaScript, hidden, or absent from the semantic page structure.
Frequently asked questions
Short answers before you make a change.
Can I use this as an H1 checker for a website?
Yes, for one public page at a time. Enter its URL to count H1 elements and inspect the H1–H6 outline in the initial HTML. It does not crawl the whole website.
Can I check an H1 tag without publishing the page?
Yes. Paste the draft HTML instead of a URL. It is sent to the server for parsing, and the check does not publish it.
Why does the H1 checker miss a visible title?
The title may be styled text or created by JavaScript after the initial response. Compare the page source with the rendered heading structure before changing it.
Must every page have exactly one H1?
One clear primary heading is a useful default, but the checker reports the evidence for review rather than enforcing an invented universal ranking rule.
Do skipped heading levels hurt rankings?
A skipped level is a document-structure clue, not an automatic ranking penalty. Review whether it makes the content harder to navigate or understand.
Does the checker render JavaScript?
No. It inspects pasted HTML or the initial public HTML response. Client-rendered headings may require a rendered-page accessibility check.
