Non-sequential headings

Opportunity severity, in the Headings tab

Why it matters

Skipping levels (H1 to H3) weakens the document outline for search engines and screen readers.

How to fix it

Nest headings in order: H1, then H2, then H3.

How Crawlune finds it

Crawlune flags Non-sequential headings automatically on every crawl and lists the affected URLs under the Headings tab, where you can filter, inspect each page and export the list to CSV. The free version crawls up to 550 URLs with every check enabled.
