Consent Mode v2 enables advertisers to recover a substantial portion of "lost" data in a privacy-compliant manner through reporting that aggregates and anonymizes the data. Although individual data from users who haven't given consent is inaccessible, the aggregated data still provides insights.

To use Google Consent Mode v2, you need to have a cookie banner in place.The functionality of Google Consent Mode v2 operates through the Consent Management Platform (CMP), receiving signals regarding user consent directly from the banner—indicating whether a user has granted consent or not.

The main difference between Google Consent Mode and Google Consent Mode v2 is the addition of two additional consent states: ad_user_data and ad_personalization, which can be attributed to the user’s consent.

The easiest way to implement Google Consent Mode v2 is to use a Google-Certified Consent Management Platform (CMP) with Google Consent Mode v2.

ad_user_data is used to set consent for sending user data to Google for advertising purposes. ad_personalization controls whether data can be used for ad personalization (e.g. remarketing).

Under the advanced implementation, Google tags are loaded before users are presented with the Cookie Consent banner, and Google collects cookieless data that lack personal identifiers. Under the basic consent mode, no information from users is collected at all, not even consent status.
