Frequently asked questions
What does the Heading Structure Analyzer flag?
Missing H1s, multiple H1s, heading level skips (for example H2 straight to H4), duplicate headings, and empty headings — plus the full H1–H6 outline in document order.
Why does heading structure matter for SEO?
Headings are the page’s outline. Search engines and screen readers use them to understand what the page is about and how its sections relate. A broken outline makes the page harder to understand for both.
What is a heading level skip?
A skip is when heading levels jump — for example an H2 followed directly by an H4 with no H3 between them. It usually means a section was added or removed without fixing the outline.
