Google Consent Mode v2

Google Consent Mode v2 allows you to adjust how Google tags behave based on the user's consent choices. This helps ensure compliance with data protection regulations while still enabling important site functionality.

Consent Mode v2 particularly impacts:

  • Cookies
  • Ad Personalization
  • Analytics Tracking

With Consent Mode v2, Google introduced two new consent signals required to comply with the EU Digital Markets Act (DMA):

  • ad_storage
  • analytics_storage
  • ad_user_data (🆕)
  • ad_personalization (🆕)

The new signals ad_user_data and ad_personalization are essential under DMA for platforms like Google Ads and should be set according to user consent.
