“My recommendation: Didomi is a reasonable CMP choice if your primary objective is reliable consent signaling across programmatic advertising partners.”
“It generates the standardized TC String.”
“Didomi supports the IAB Transparency and Consent Framework and exposes the standard tcfapi interface.”
“Didomi supports Google Consent Mode v2, including the important signals:”
“It supports Google's Additional Consent framework for Google Ad Tech Providers that aren't on the IAB Global Vendor List.”
“Didomi's CMP is registered with IAB Europe (CMP ID 7).”
“Importantly, Didomi also advertises support for the latest TCF 2.4 requirements, including its October 2026 web transition.”
“For Google Ad Manager specifically, Didomi provides troubleshooting instructions to inspect ad requests for gdpr_consent and gdpr parameters and validate the TC String.”
“These partners may need custom integrations, consent APIs, or tag-manager rules. Simply configuring them in Didomi doesn't guarantee that they receive or respect consent correctly.”
“It does not automatically derive every Google Consent Mode signal from the TC String. For example, analytics_storage requires separate configuration.”
