Data privacy has become a hot topic, and companies are struggling to find a balance between collecting essential data and respecting users’ privacy rights. Google, the undisputed leader in technology and online advertising, has taken a significant step forward with the introduction of Google Consent Mode V2 at the end of November 2023. This updated version of the original Consent Mode not only redefines how websites communicate users’ consent preferences to Google tags, but also sets a new compliance standard that must be met by March 2024.

What is Google Consent Mode V2?

Google Consent Mode V2 represents a significant innovation in the digital ecosystem, marking a crucial evolution in how websites manage user consent for data collection. This advanced version has been designed to address the increasingly complex compliance and privacy needs in the online space, providing a robust and flexible solution for adapting the behavior of Google tags and scripts based on users’ expressed consent preferences.

Through Google Consent Mode V2, websites can now communicate effectively with Google services, ensuring that user data is processed in full compliance with user choices. This is particularly relevant in the context of strict privacy regulations such as GDPR in the European Union, giving websites the tools they need to navigate these requirements without compromising the quality of data collected for analytics and advertising.

Relationship between consent rates and conversions modelled

Is essential to understanding the impact of privacy policy on the performance of a marketing campaign. It is important to note that conversion rates are strongly influenced by the consent status of users. Extensive studies have found that users who have provided consent typically have a significantly higher likelihood of conversion, with figures that can reach 2 to 5 times higher than for users without consent. However, it is essential to understand that these figures can vary considerably depending on a number of factors, including user consent rates, the industry in which the business operates and the type of conversion targeted. Thus, marketing strategies need to be tailored accordingly to maximise consent rates and therefore conversions, while ensuring that the privacy policy is transparent and appealing to users.

Features and key points

With the introduction of Google Consent Mode V2, Google has added two new parameters, ad_user_data and ad_personalization, which expand the ability of websites to manage user consent in a more detailed and nuanced way. These new parameters allow for advanced personalization of the user experience, ensuring that advertising and data collection are precisely tailored to the preferences expressed.

ad_user_data focuses on controlling the transmission of user data to Google for advertising purposes, based on explicit user consent. This parameter ensures that personal data is collected and used only when there is clear consent from the user, increasing transparency and trust.

ad_personalization manages the activation of personalized advertising (remarketing) based on user consent. Through this parameter, websites can provide a more relevant and engaging advertising experience for users while respecting their privacy preferences.

These new parameters offer significant flexibility in managing consent, allowing websites to align with strict legal requirements without sacrificing the effectiveness of advertising and analytics.

Importance of upgrading to Google Consent Mode V2

Upgrading to Google Consent Mode V2 is essential for website owners and advertisers alike. First and foremost, this update is a crucial way to ensure compliance with privacy regulations such as GDPR, providing site owners with a robust solution for managing user consent. By implementing Google Consent Mode V2, they can rest assured that user data is treated in accordance with the strictest data protection standards, which helps to increase user trust and loyalty.

Secondly, Google Consent Mode V2 gives site owners the ability to manage data more effectively and earn users’ trust. Through improved data management, they can offer users more personalised and transparent options for consenting to the collection and use of their data. This increased transparency and control over data helps to strengthen users’ trust in websites and associated brands, ultimately leading to a more positive online experience and more lasting relationships between users and website owners.

How it affects digital marketing

The implementation of Google Consent Mode V2 has a profound impact on digital marketers, especially in the European Economic Area (EEA), where data protection regulations are among the strictest in the world. This new consent mode provides an essential solution for navigating the complexity of these regulations while ensuring that digital advertising strategies remain effective and compliant.

For digital marketers, Google Consent Mode V2 represents an opportunity to improve transparency and accountability in advertising campaigns, strengthening trust between brands and consumers. By adapting advertising strategies to users’ consent preferences, agencies can ensure more ethical and efficient data collection while optimising campaign performance.

Furthermore, Google Consent Mode V2 allows agencies to minimize data loss and improve measurement accuracy, even in scenarios where cookie consent is limited or absent. This is achieved by using aggregated and anonymised data to shape user behaviour, providing a solid basis for informed marketing decisions, even in an increasingly privacy-focused digital landscape.

Comparing V1 and V2: Advantages of Google V2 consent mode

The comparison between Google Consent Mode V1 and V2 highlights the substantial advantages of the V2 version. A significant improvement is the detailed consent management offered by V2. While V1 only offered the general option to accept or reject all cookies, V2 allows users to provide consent specifically for various types of cookies and tracking technologies used on websites, including for personalized advertising or user analytics purposes. This granular approach allows site owners to respect individual user preferences in a more accurate and transparent way, helping to build trust in the online experience.

In addition, version V2 of Google Consent Mode integrates more tightly with Google products, making it easier to set up and use them. Through this tighter integration, site owners can achieve better data synchronization and greater efficiency in managing and optimizing their online campaigns. For example, integration with Google Analytics enables more accurate collection and analysis of user data, while integration with Google Ads facilitates more efficient personalisation and management of advertising campaigns. In summary, Google Consent Mode V2 brings a number of significant improvements that increase flexibility, transparency and efficiency in managing user consent and online marketing campaigns.

Advantages over previous version

Google Consent Mode V2 brings a number of significant improvements over its previous version, giving websites and digital marketers unprecedented control and granularity in managing user consent. These benefits are essential in today’s environment, where privacy regulations are increasingly stringent and users’ expectations for transparency and control over their personal data are growing.

Difference between basic vs. advanced implementation


Improved control

Google Consent Mode V2 allows website owners to adjust and optimize data collection based on the specific consent given by each user. This level of detailed control over data collection is crucial to ensure compliance with privacy legislation, such as GDPR, and to meet the increasingly complex requirements of national and international regulations. By customising how data is collected and used based on user consent, websites can reduce the risk of non-compliance and avoid potential sanctions.

Improved granularity
The introduction of the new parameters, ad_user_data and ad_personalization, in Google Consent Mode V2 provides unprecedented granularity in managing consent preferences. This means websites can more clearly distinguish between different types of consent, such as consent for analytics data collection versus consent for personalised advertising. This differentiation allows a more precise alignment with user preferences and a finer tailoring of marketing strategies, ensuring that advertising messages are relevant and well received by the target audience.

Implementing Google Consent Mode V2

It is a complex process that requires a methodical approach and technical expertise. Digital marketing agency re7consulting provides the support needed to navigate this transition, ensuring compliance and optimizing digital performance.

This step ensures that all Google tags are updated and compatible with the new version of Google Consent Mode, and the implementation is tested and validated for proper functioning.

Improved conversion modeling is another key aspect of Google Consent Mode V2, allowing companies to compensate for the lack of direct tracking data by using aggregated and anonymized data.

Meeting deadlines

A crucial aspect of the transition to Google Consent Mode V2 is meeting the implementation deadline. Companies and websites using Google services have until March 2024 to ensure that the Google Consent Mode V2 implementation is complete and functional. This deadline is essential as it ensures compliance with existing legal and ethical requirements, avoiding potential penalties and ensuring a smooth transition to the new privacy standards. Meeting this deadline is vital for maintaining the effectiveness of digital marketing campaigns and protecting user privacy in accordance with the latest regulations. It is therefore imperative that organisations start the implementation process as soon as possible to ensure that all technical and compliance issues are addressed before the March 2024 deadline.
