Self-check the rest
Some things — like whether "Reject all" is one click, same size as "Accept all" — need a human look, and we tell you exactly what to check.
What we check
- Detects 12 named consent-management platforms from the served page source: Cookiebot, Usercentrics, Iubenda, CookieYes, Complianz, Borlabs, OneTrust, Termly, Cookie Notice, Moove GDPR, Didomi and Quantcast Choice.
- Checks for an IAB TCF (Transparency & Consent Framework) signal and a Google Consent Mode signal, and grades A–F from a combined score of the three.
- Lists four things that genuinely need a human look and cannot be automated: whether “Reject all” is one click at the same layer as “Accept all”, whether the two buttons are equally prominent, whether any non-essential box is pre-ticked, and whether the banner actually blocks tracking scripts until a choice is made.
