A footer link leads to a 404 — on every page of the site
A product link in the footer is present on all 16 checked pages. It responds with a 302 redirect to a documentation page, which in turn answers 404 Page Not Found.
Why this class is dangerous: a one-level link check sees the 302 and counts the link as alive — the defect is only visible when you follow the whole redirect chain.
About the severity: coverage is maximal (16 of 16 pages), but the destination is technical documentation rather than a conversion path, so Medium instead of High. There is a cumulative effect to keep in mind: a 404 in the footer of every page affects search-engine assessment and the impression of the developers this link is aimed at.
Steps to reproduce
- Open any page of the site
- Scroll to the footer and click the product link
- A 404 page opens

Evidence: Redirect chain and final HTTP status captured for every link
