Is it a problem to have multiple h1 tags?

Generally, SEO best practice is to use only one h1 per page. If there are multiple, the structure may need review.

Does this detect content rendered by JavaScript?

No — only the initial HTML returned by the server is analyzed, so headings added later via client-side rendering may not be detected.

Is the URL I check stored?

No. Every request is checked immediately and nothing is stored.

Is multiple h1 a problem?

HTML5 allows it, but one is recommended so the page topic stays clear for SEO and accessibility.

TITLE differs from h1 — an issue?

Not required to match, but consistent intent helps search engines.

URL

How to use

Enter the URL to check.
Click the "Extract" button.
The TITLE and the h1-h6 heading structure are shown hierarchically.

🎯 Use Cases

Check the heading tag structure during an SEO audit

Check for duplicate or missing h1 tags

Example

Input

https://example.com/

Output

TITLE (14 chars): Example Domain
H1  Example Domain

example.com has a minimal structure with just a TITLE and a single h1, so the result shows the TITLE character count (14) and the one H1 heading. This is an illustrative sample; actual results vary by the target page's structure.

Heading structure checkpoints

TITLE and h1–h6 tell search engines and screen readers what the page is about.

Item	Recommended
TITLE	Search result title — 50-60 characters
h1	Main page heading — one per page
h2–h6	Section hierarchy — skipping levels (h1→h3) confuses structure
Duplicates & gaps	Repeated text and empty heading tags are worth checking too
