Frequently asked questions
- Is Heading Structure Checker free to use?
- Yes. Heading Structure Checker is available on the free plan with 20 daily runs. Paid plans add higher quotas for repeat work.
- How many H1 tags should a page have?
- One, describing the page's main topic. Multiple H1s are not a penalty, but they make the document outline ambiguous.
- Do heading levels have to be consecutive?
- They should be. Jumping from H2 to H4 breaks the outline used by screen readers and by content extractors.
- Do headings help with AI search?
- They do. Answer engines lift the passage under a heading, so phrasing a heading as the question makes that passage easier to quote.
- Should headings be styled text or real heading tags?
- Real tags. Text that only looks like a heading carries no structure at all, which is invisible on the page and obvious to a crawler.
