Should I have more than one H1 on a page?

It is recommended to have only one H1 tag per page representing the main topic. Multiple H1 tags can dilute keyword relevance and confuse crawlers.

What is a skipped heading level?

A skipped level occurs when you jump levels improperly, e.g., jumping from an H2 tag directly to an H4. This breaks accessibility guidelines and complicates readability.

Does this tool work on local environments?

Yes. Since OneClickSEO runs locally in your browser, it can scan headings on localhost, staging URLs, and password-protected intranets.

Q: Why does heading hierarchy matter for SEO?

Search engines use headings to understand the context and structure of your content. A correct hierarchy (H1 -> H2 -> H3) signals high-quality organization and makes it easier for crawlers to parse.

Visualize and validate your H1-H6 heading outline instantly. Identify skipped levels, missing H1 tags, and structural issues to improve SEO and accessibility.
