About the Heading Checker

The Heading Checker lists every H1 to H6 heading of a page in order, as an indented outline you can copy. It flags a missing H1, several H1s, levels that skip a step (H2 straight to H4), empty headings, headings over 120 characters and repeated headings. A clear heading outline helps readers skim, lets screen reader users jump between sections, and gives search engines and AI answers clean section boundaries to quote.

Our server requests the URLs you enter, like a crawler: it reads the response without running the page's scripts, and the analysis runs in your browser. The URLs and results are not stored.

How to use the Heading Checker

  1. Enter the page URL.
  2. Press Check headings and read the outline: it should read like a table of contents.
  3. Fix the failed checks: add one H1 that names the topic, fill or remove empty headings.
  4. Replace skipped levels with the next level down and style them with CSS if they should look smaller.

Frequently asked questions

Can a page have more than one H1?

Google has said several H1s do not cause a ranking problem. One H1 is still the clearest structure for readers and screen readers, so use one main heading and H2s for the sections.

Do headings help SEO?

They help search engines understand what each part of a page is about, and Google often uses headings to pick featured snippets and jump links. Most of all they make long content easier to read, which keeps visitors on the page.
