Quick Summary

Consent Mode v2 lets Google tags adjust behaviour based on user consent choices. Two new required parameters: ad_user_data and ad_personalization (in addition to existing analytics_storage and ad_storage). Implement via a Consent Management Platform (CMP) that supports Consent Mode (Cookiebot, OneTrust, Usercentrics), or manually using GTM's consent settings. Set default consent state (denied for EU, granted for regions without consent requirements), integrate your CMP to update consent state when users make choices, and configure all Google tags to respect consent settings.
