Implementing Google Consent Mode V2

Google Consent Mode V2 is essential for maintaining compliant analytics and advertising while respecting user consent choices. This guide walks you through the complete implementation process.

What is Consent Mode V2?

Consent Mode allows Google tags to adjust their behavior based on user consent status. V2 introduces new parameters for EEA users:

gtag('consent', 'default', {
  'ad_storage': 'denied',
  'ad_user_data': 'denied',
  'ad_personalization': 'denied',
  'analytics_storage': 'denied',
  'wait_for_update': 500
});

2. Update Consent on User Action

gtag('consent', 'update', {
  'ad_storage': 'granted',
  'ad_user_data': 'granted',
  'ad_personalization': 'granted',
  'analytics_storage': 'granted'
});
