Google is introducing significant changes to the way its advertising and analytics products operate across EEA and UK markets. Utilizing a Google CMP (Consent Manager Platform) partner ensures best practices are followed to maintain functionality.
Starting March 2024, Google’s “EU Consent Mode V2” is mandatory for certain Google products ensuring users’ consents are collected before being able to utilize certain functionality in Google’s products.
What’s the history of Google Consent Mode V1 and V2?
The EU Google Consent Mode V1 was optional and was first introduced in 2015 to improve compliance with data privacy laws for advertising purposes. It included a revision of how Google tracks and optimizes data for programmatic advertising strategies.
The EU Google Consent Mode V2 is now required for tracking and using a Google-certified Consent Management Platform (CMP) ensures that your experience follows best practices. Google tracking takes place only when consent has been given via the enabled Google Consent Mode consent manager experience. It is important to ensure that the configurations and implementations of your consent experience are accurate with your Google Tag Manager.
TrustArc’s knowledgeable and highly skilled Technical Account Management team can ensure that your TrustArc Google Consent Mode experience is correctly configured and functioning as intended for compliance and optimal advertising experience.
How does Google Consent Mode work?
Google Consent Mode can be deployed on a site in one of two methods – a Basic or Advanced deployment. With a Basic deployment, Google Tags are not fired until the user opts in. With an Advanced deployment, Google Tags continuously fires cookieless pings until consent is given. You can learn more in Google’s documentation here.
Who is impacted by the mandatory EU Google Consent Mode V2 requirement?
Organizations deploying cookies or trackers for behavioral or targeted ad marketing/ remarketing in Europe should pay attention! This impacts organizations using Google tools: all Google Ad Services (Ad Mob, Ad Serve, Ad Manager), Google Analytics, and Google Tag Manager.
What is the impact?
Organizations not using Google Consent Mode V2 will experience measurement loss affecting marketing campaigns. Impacting all your advertising activities, campaign optimization, and conversion metrics.
Why the change?
Google has made an important change to its advertising tools, including Google Ads. The Consent Mode will become mandatory for all users starting from March 2024. Companies utilizing Google Ads will need to implement Google Consent Mode to avoid the blocking of personalized ads such as remarketing. In the future, Google plans to block conversion tracking as well for those who don’t comply.
