FAQ

Heading Structure Checker questions.

Practical answers about live URL checks, heading levels, H1 usage, skipped levels, and reports.

A Heading Structure Checker extracts H1, H2, and H3 headings from a page and checks whether the heading hierarchy is clear and logical.

Yes. The tool is designed to check live page URLs. It should not be described as scanning staging, private, or password-protected URLs unless that functionality is confirmed.

The tool checks H1, H2, and H3 headings.

The H1 usually represents the main topic of the page. A clear H1 helps users and editors understand the page focus quickly.

In most cases, one clear H1 is recommended. Multiple H1s should be reviewed and adjusted if they reduce structural clarity.

Skipped levels happen when the structure jumps, such as H1 directly to H3 without an H2.

Long headings can be harder to scan and may reduce readability. The tool flags headings above the selected character threshold.

Yes. You can copy heading text, copy headings as Markdown, copy issue data, or copy raw extract data.

Yes. Use Download Report when you need to share the heading audit with a content team, developer, client, or SEO reviewer.

No. This tool focuses on heading structure. For a complete review, use Wranker’s On-Page SEO Checker or Website SEO Analyzer.
