What is CMP in Google AdSense?

In Google AdSense, CMP stands for Consent Management Platform. It collects users’ privacy choices and communicates the relevant consent signals to Google and advertising vendors.

For publishers serving personalized ads:

• EEA and UK: A Google-certified CMP integrated with the IAB TCF has been required since January 16, 2024.

• Switzerland: The same requirement has applied since July 31, 2024.

• Consent signals: The CMP communicates vendor and purpose choices through the IAB TCF framework.

Google certification confirms that the CMP meets Google’s certification criteria; it does not by itself guarantee full compliance with applicable privacy laws.
