Heading Analyzer

Workspace

The NOFYI Heading Analyzer validates a website address you enter and explains what would be needed for a full heading analysis. Paste a URL, click Process, and the tool checks the address and shows a short result. It does not list the H1-H6 headings on that page.

Use it as a quick format check before you use a dedicated SEO or accessibility tool that can fetch and parse the page. A real heading audit depends on reading the page HTML, so a browser-only tool cannot produce it from one URL alone.

How to Use the Heading Analyzer

  1. Open the Heading Analyzer page.
  2. Type or paste a full URL into the Enter URL field, including https://, for example https://example.com.
  3. Click Process.
  4. Read the result in the Result panel. Use Copy to copy it or Download to save it.
  5. Click Clear to empty the workspace and start over.

Worked Example

Input: https://example.com

Observed output:

  • URL: https://example.com
  • This analysis requires server-side processing to crawl and analyze the website. Client-side analysis is limited by CORS restrictions.
  • Domain validated: example.com

No heading list, heading count, H1 count, skipped-level warning, or empty-heading warning was shown. The only confirmed result for this input was that the domain example.com validated.

Limitations

  • Does not return a heading list. Despite the tool name, the observed result contains no H1, H2, H3, H4, H5, or H6 headings.
  • Does not check for a missing H1, multiple H1s, skipped levels, or empty headings.
  • Cannot fetch and parse another site from the browser alone; the tool itself says server-side processing is required and client-side analysis is limited by CORS restrictions.
  • Validation is limited to the address you enter. It does not confirm that the page has a sensible heading structure.
  • Nothing is saved between sessions. Copy or download your result before leaving the page.

Frequently Asked Questions

Does this tool list my page headings?

No. In the observed test with https://example.com, it returned only a validation message and a note that server-side processing is required. It did not list any headings.

What should I enter?

Enter a full URL including https://, such as https://example.com. The tool validates the domain from that address.

Why can it not read headings from my browser?

Browser security rules (CORS) prevent a page on one site from freely fetching and parsing another site’s HTML. A full heading audit needs server-side fetching or a browser extension.

Is my URL sent to a server?

The observed result does not show an external fetch or heading data. Treat the workspace as a local format check, and do not enter private or sensitive URLs you do not want to share.
