A few weeks ago, we talked about what consent mode is and shared important details on the topic. As promised, we're keeping you updated on any new developments. Recently, Google Analytics announced major changes to Consent Mode, introducing version 2 (V2). Although there hasn't been an official announcement, and sometimes it's difficult to find concrete details about this news, we're sharing this sample hard-to-find update from Google Ads product with you.

In this blog post, our aim is to ensure you understand the recent changes and what they mean for you.
If you haven't read our blog post explaining what GA4 Consent Mode is, I suggest you do so before continuing further.
What is Consent Mode?
We’ve talked about this in our previous post, but just a brief context - this feature allows you to manage data collection and usage in accordance with user consent preferences. This Google Analytics feature adjusts how GA4 works depending on whether users give permission for their data to be collected. It makes sure data is only collected when users agree, and it uses smart methods (Behavior Modelling) to still get useful information for those who choose not to share their data. This way, it helps gather the most valuable insights while being respectful of user privacy preferences.
What's the reason behind upgrading to GA4 Consent Mode V2?
Google upgraded Consent Mode to Consent Mode v2 to address the evolving landscape of data privacy. V2 offers users more granular control over their data, strengthens transparency around data collection practices, and improves data quality in GA4 reports. This not only encourages user trust but also ensures Google's platforms can adapt to future privacy regulations while maintaining core functionalities for analytics and advertising.
Let me briefly explain it using this scenario: Imagine your website is a store, and user data is like customer information. The old way (Consent Mode) was like asking everyone who walks in if you can track them around the store. Now (Consent Mode v2), it's like asking if you can track them for product recommendations (analytics) and if it's okay to use that info for future promotions (advertising). This gives people more control, builds trust (they know what's happening with their info), and helps the store keep track of things more accurately (better data). Google upgraded it to keep up with changing privacy rules and make sure their system works smoothly in the future.
What differences should we expect in GA4 Consent Mode V2?
Here's a breakdown of the key differences:
- User Consent Options/Control
- Consent mode (Original): Limited
- Consent Mode v2 offers users more granular control over their data by allowing them to choose consent for website analytics and advertising purposes separately.
- Additional Parameters
- Consent Mode (Original): None
- Consent Mode v2 introduces new parameters like ad_user_data and ad_personalization, giving users more control over how their personal data is used.
- Integration and Accuracy
- Consent Mode (Original): Less clear consent signals
- Consent Mode v2 transmits clearer consent signals to Google Ads, ensuring ad targeting respects user choices and improves conversion measurement accuracy.
- Advanced Features
- Consent Mode (Original):Not available
- Consent Mode v2 offers an optional Advanced Consent Mode that allows collecting anonymized data even without explicit consent for modeling purposes. This requires careful consideration of user privacy.
In summary, Consent Mode v2 is a significant upgrade that provides a more robust framework for user consent management, improved data privacy controls, and a stronger connection with Google Ads for more accurate advertising and measurement.
Is GA4 Consent Mode V2 Mandatory?
Yes. As of March of 2024 GA4 Consent Mode V2 has become Mandatory for all websites who use Google Analytics 4, Google Ads or Floodlight (DoubleClick) tracking pixels on their website and apps.
What will happen if I haven't implemented GA4 Consent Mode V2 yet?
While there's a lot of discussion about what might happen, what's certain is the following:
- You won't be able to collect data about new users in the European Economic Area (EEA) for functionalities like advertising personalization and remarketing. This significantly hinders audience building and targeted advertising efforts for users in this region due to a lack of consent signals.
- Without clear consent information, data collected in GA4 might be incomplete or inaccurate. This can lead to misleading reports and difficulty understanding user behavior on your website.
- Features like audience building, remarketing, and conversion tracking in GA4 and Google Ads rely on user consent. By not implementing Consent Mode v2, these features might become unusable or severely limited.
- Data privacy regulations are constantly evolving, and failing to comply with them could lead to fines or penalties. Consent Mode v2 helps ensure compliance with these regulations. But please note that it would be best to talk to your legal team about the compliance risks topic.
How can I Implement GA4 Consent Mode V2?
There are two main ways to implement GA4 Consent Mode v2:
- If you're using a Consent Management Platform (CMP) to manage user consent across your website, it might offer a native integration with GA4 Consent Mode v2. This simplifies the process as the CMP handles most of the technical aspects. You can also visit the website of CMP partners if you're interested in exploring this approach.
- If you're not using a CMP or prefer a manual approach, you can implement Consent Mode v2 using Google Tag Manager (GTM) or directly through JavaScript code snippets provided by Google Analytics. These methods require some technical knowledge of GTM or JavaScript.
Here's a tip: While the process might seem technical, there are many resources available to guide you. Consider your technical expertise and choose the implementation method that best suits your comfort level. Don't hesitate to consult additional resources or seek help from a web developer if needed.

Final Word
Google's upgrade to Consent Mode v2 represents a significant leap forward in safeguarding user privacy and enhancing transparency in data practices. With V2, users gain more precise control over their data, fostering greater trust between websites and their visitors. By likening it to asking permission for specific purposes within a store, we can grasp its essence: empowering users while ensuring accurate data collection. This upgrade not only aligns with evolving privacy regulations but also future-proofs Google's platforms for continued functionality in analytics and advertising. It's a win-win scenario, where privacy is respected, trust is fostered, and data remains accurate and valuable.
