Heading Structure Analyzer — Frequently Asked Questions
- What does the heading analyzer check?
- It extracts every H1–H6 on a page and flags missing levels, multiple H1s, and skipped hierarchy.
- Can a page have more than one H1?
- HTML5 allows it, but most SEO and accessibility audits expect a single primary H1 per page.
- Why does heading order matter?
- Screen readers and search engines use heading order to map document structure — skipped levels confuse both.
