Defining Consent Mode V2

The Concept of Consent Mode V2

The digital landscape is shifting, and privacy regulations are at the forefront. Google’s response? Introducing Consent Mode V2, a crucial update to their data collection framework. This upgrade, driven by evolving privacy laws, says goodbye to mobile device identifiers and third-party cookies (with Chrome phasing out the latter in 2024).

But fear not, businesses! Consent Mode V2 isn’t here to shut you down. It’s your key to unlocking user behavior insights and maximizing marketing efforts. By March 2024, it becomes mandatory for anyone using Google Ads products in the European Economic Area (EEA). Skipping this step means no new users from the region and a halt to remarketing across Google Ads, Floodlight, and Display.

So, what’s the hold-up? Consent Mode V2 empowers you to navigate the privacy landscape responsibly while still measuring performance and engaging audiences.

Google Consent Mode V2 Key Features

Websites, rejoice! Google Consent Mode v2 streamlines GDPR compliance with its focus on granular consent. Think of it as offering users a menu of data-sharing options, not just a yes/no switch.

Gone are the days of all-or-nothing data collection. V2 introduces two key parameters:

  • ad_user_data: This lets users decide if their data can be used for advertising purposes. Users can say “yes” to relevant ads without giving up all their information.
  • ad_personalization: This empowers users to control whether they see personalized ads. Want ads based on your interests? Opt in! Prefer generic ads? No problem!

The Consent Mode V1, have two parameters tags which are analytics_storage and ad_storage related to data collection. The Consent mode V2 paramaters ad_user_data and ad_personalization tags are related to how data is shared and used.

Basic Understanding on Consent Mode V1 vs Consent Mode V2

Consent Mode V2 have offers two levels of implementation: Advanced Consent Mode and Basic Consent Mode

Basic Consent Mode:

Privacy comes first: Unlike other modes, Basic Consent Mode doesn’t collect any data, not even consent status, until users explicitly give their permission. This ensures maximum user privacy.

Tags stay blocked: No Google tags load until consent is granted. This means no tracking, no analytics, and no ads until users say yes.

Conversion modeling to the rescue: Even without consent, Basic Mode still tracks conversions and uses modeling to estimate missing data based on consenting users. This offers insights, but accuracy might be lower.

Better than no Consent Mode: Although not perfect, Basic Mode provides valuable insights while respecting user privacy. It’s a good starting point for privacy-conscious businesses.

Advanced Consent Mode:

Early bird gets the tag: Google tags load before the consent banner, allowing data collection even without consent. But wait, there’s a twist!

Cookieless data, anonymous and free: Collected data lacks personal identifiers like names or addresses. Think of it as broad strokes instead of detailed portraits.

Modeling for accuracy: Google analyzes factors like device type, country, time of day, conversion type, and browser type to improve the accuracy of its estimates.

Think of it like this: Imagine a crowd. While you don’t know each person, observing their movements and characteristics can paint a picture of the crowd’s behavior.

Google Consent Mode v2: Don’t Miss the March Deadline (or Face the Consequences)

While the exact consequences of skipping Google Consent Mode v2 (GCM v2) by March 2024 are still evolving, the picture isn’t pretty:

  • EU audience vanishes: Say goodbye to data on new European users. Analytics and Ads go blind, potentially crippling your targeting and remarketing.
  • Marketing magic disappears: Links between Google Analytics 4 and Ads features crucial for audience building and remarketing may cease to function.
  • Conversion tracking might wobble: While not entirely clear, conversion tracking could be impacted, leading to unreliable data.

The takeaway? Don’t gamble with your marketing success. Implement Basic Consent Mode ASAP, even if details are still unfolding. It’s about future-proofing your campaigns, respecting user privacy, and staying compliant.


In summary, Consent Mode V2 represents a significant evolution from the original Consent Mode, offering enhanced features and greater flexibility for website owners and users alike. By understanding the key differences and improvements, stakeholders can better navigate the complexities of user consent in the digital age. As privacy regulations continue to evolve, the adoption of Consent Mode V2 embracing this advanced framework not only demonstrates a commitment to privacy but also ensures a more transparent and trust-building experience for users.
