The launch of Google Consent Mode v2 signifies a major step in Google’s attempts to balance the needs of advertisers to collect user data with the rights of users to maintain their privacy. Unveiled in late November 2023, Google Consent Mode V2 is an evolved version of its predecessor and comes with a number of key new features.
In this article, we’re going to explore this new incarnation, its implications for server-side tracking, its correlation with the Digital Markets Act, and the role that cookie banners play in compliance.
Key features of Consent Mode V2
Elevating User Privacy
Google Consent Mode V2 introduces two new parameters, ad_user_data and ad_personalization, alongside the existing analytics_storage and ad_storage. These parameters play a key role in enhancing user privacy, offering website owners more refined control over the transmission of user data to Google, particularly for advertising purposes.
The ad_user_data parameter allows control over whether user data can be sent to Google for advertising purposes, while ad_personalization governs the activation of personalized advertising, including remarketing efforts.
These additions highlight Google’s commitment to providing users with greater control over their data and aligning data transmission with explicit user consent. Notably, these settings impact services such as Google Ads, Google Shopping, and Google Play.
Two Implementation Options
Google Consent Mode V2 offers a dual approach to implementation – Basic and Advanced.
Basic Consent Mode V2 Implementation
This straightforward approach involves normal data collection and tag firing when users consent to cookies. Conversely, when users reject cookies, data collection halts, and cookieless pings are not sent. While simple, this approach significantly limits data collection when users choose not to consent.
To implement Basic Consent Mode V2, website owners need to:
Basic Consent Mode V2 Implementation
A more involved approach, this implementation permits the sending of anonymous, cookieless pings to Google for modeling purposes, even when users do not consent to cookies. This consent method allows websites to recover some data for Google Ads and GA4, offering a more resilient data collection mechanism.
To implement Advanced Consent Mode V2, the steps involve:
The legal landscape and Digital Markets Act (DMA)
The implementation of Google Consent Mode V2 is intricately tied to legislative requirements, notably the Digital Markets Act (DMA). In the context of digital advertising and data privacy regulations, the DMA mandates “gatekeepers” like Google to obtain explicit consent for the collection and use of personal data of European citizens.
Failure to adopt Consent Mode V2 by the mandatory deadline of March 2024 could result in a significant gap in data capture for new users from the European Economic Area (EEA). This not only highlights the importance of compliance but also emphasizes the potential impact on advertising strategies and efficacy for businesses using Google Ads and GA4.
Cookie banners & ensuring compliance
To implement Google Consent Mode V2 effectively, having a compliant cookie banner is essential. This banner, facilitated by a Consent Management Platform (CMP), serves as the communication bridge between user consents and Google. The language used in the banner must align not only with Google’s compliance standards but also with GDPR and the e-privacy directive.
When a user consents, the cookie banner communicates this decision to Google via the Consent Mode, allowing normal data collection. Conversely, if consent is rejected, Google adjusts data collection for those users. In this scenario, Google employs conversion modeling, utilizing machine learning to infer connections between user interactions and conversions.
Server-side tracking – dispelling some common misconceptions
A widespread misconception is that server-side tracking negates the need for user consent. However, under the General Data Protection Regulation (GDPR) and the EU User Consent Directive, explicit and informed consent for data processing is mandatory, regardless of whether tracking occurs on the server side.
When integrating Consent Mode with server-side tracking, it is crucial to ensure that user consent is respected on both the client-side (browser) and server-side. This comprehensive approach involves configuring Consent Mode in web Google Tag Manager, passing user consent from web GTM to server-side GTM, and setting up server-side tags to align with user consent decisions.
Treading carefully in Advanced Consent Mode
The “Advanced Consent Mode” introduces the practice of transmitting signals to Google services from users who have not given explicit consent. While this can enhance data modeling for GA4 and conversion tracking in Google Ads, businesses should exercise caution and consult legal teams regarding the ethical implications of collecting data without user consent.
Additionally, considerations should be made for potential brand image consequences, as visitors with a slightly more in-depth understanding of the processes involved may perceive the detection of Google signals without consent as intrusive.
The new balance between data-driven insights and privacy compliance
Google Consent Mode V2 provides advertisers and website owners with a flexible tool to tailor their data collection strategies based on user consent, effectively balancing the demands of privacy compliance and data-driven insights. The integration of server-side tracking with Consent Mode V2 offers more control over data flow, ensuring not only compliance with user consents but also enhancing the resilience and accuracy of data collection.
For businesses, especially those catering to the European Economic Area, it is imperative to assess traffic, collect user consent via a Consent Management Platform, and meticulously set up Consent Mode V2. This proactive approach not only ensures compliance with regulations but also safeguards the quality of audience and measurement data, contributing to more effective and ethically sound digital marketing strategies.
As businesses find themselves having to steer through an increasingly complex landscape of data privacy and advertising regulations, embracing Google Consent Mode V2 is a strategic necessity for sustainable and responsible digital marketing practices.
