How to use the Heading Checker

  1. Enter the page URL.
  2. Run the check.
  3. Read the heading tree and fix any missing H1, repeated H1, skipped level, or empty heading issues.

How it works

This check runs on our server. The page address is used only for this check and is not stored.

The tool fetches one page, reads the HTML, and extracts every h1 through h6 element in source order. It then builds an outline tree and checks for structural issues such as no H1, more than one H1, skipped levels like H2 to H4, empty headings, and very long headings.

Because no JavaScript runs, the outline reflects the server response rather than any headings added later in the browser.

Examples

  • A page that jumps from H1 to H3 gets a skipped level warning.
  • A page with two H1 tags can still render fine, but the checker flags the duplication so you can simplify the structure.
  • An empty heading used only for spacing is reported because it adds noise for screen readers and search tools.

Limitations

  • The tool checks one page only.
  • It cannot tell whether the visible design makes a heading look too large or too small. It only reads the HTML structure.
  • JavaScript-generated headings are not counted because the check does not render the page.

Frequently asked questions

Is more than one H1 always wrong?

Not always, but it often makes the page structure less clear. Most pages are easier to understand with one main H1 and lower levels beneath it.

Why do skipped heading levels matter?

They can make the outline harder to follow for both readers and assistive technology. A logical order also helps keep the page easier to scan.

Does heading order affect rankings directly?

There is no fixed ranking bonus for a perfect outline, but clear headings help search engines and visitors understand the page.
