Google Consent mode v2 allows you to signal the consent status of your users, adapt Google tag behavior accordingly, and enables Google to model for gaps in conversions. It is important to choose the default consent state, which is applied before the user makes any selection regarding the cookie usage. Consent mode allows you to communicate your users’ consent choices made on consent banners to Google tags or SDK so that they can adjust their behavior accordingly. This allows you to respect user privacy choices when measuring conversions and remarketing users.

There are two types of Google consent mode: Basic and Advanced.

  • Basic Consent Mode: Google tags are blocked before users grant consent. Consent Mode has been implemented, but data is collected only from consented users when they grant user consent. If users deny cookie consent, Google tags do not fire at all.

  • Advanced Consent Mode: Consent Mode has been implemented, and data is collected from both consented and non-consented users, when they grant consent and when they deny consent. Google tags are not blocked before users make their consent choices. All tags are fired and sent to Google Analytics 4 (GA4):
    If users grant cookie consent, cookies are set on users' devices and send user data to GA4.
    If users deny cookie consent, cookies are not set, but cookieless pings are used instead, which send anonymized data to GA4.

Basic Consent Mode implementation provides simpler consent management, is easier to setup and requires less customization of the functionality of Google Tags.

Advanced Consent Mode implementation is the default consent mode at GTM. It provides website owners with enhanced customization and control over consent management, allows them to collect more user information, and enables improved modeling.
