What gets tested
The scanner searches the scanned page's HTML for a link to the privacy policy: by path (/privacy-policy/, /datenschutz/ and variants) or by visible link text. The hit gets fetched. The page it reads doubles as the source for the privacy policy match, which holds the text against the detected tracking stack.
Why it matters
Every tool that processes personal data needs its explanation in the privacy policy. The first step towards that is banal and still frequently missed: the page must be findably linked and technically reachable. A 404 behind the footer link goes unnoticed internally for years. Visitors and supervisory authorities notice.
Common causes
- The footer is injected via JavaScript, so the served HTML carries no link.
- Relaunch: the policy still lives under the old path, the link points at nothing.
- The policy sits on a different domain (parent company, site-builder default) and is not recognisable as the site's own page.
