In February 2024, Google released an update to its consent mode for Europe, introducing additional parameters to ensure greater privacy and control over user data processing. Marketers have dubbed the update “Consent Mode 2.0,” although this specific phrasing is absent from Google’s original announcement. In this article, we’ll delve into how this impacts web analytics and what website owners should do in response to this update.
Impact of the Update
Consent Mode is a set of rules governing user privacy. Currently, these rules require website owners to conduct surveys among users and obtain their consent for data usage within analytics and marketing realms. Additionally, site owners must provide the option to opt out of data collection.

Impact on Users
Essentially, a long-standing practice of users freely providing any information about themselves to a website in exchange for accessing content is disrupted. Now, Europeans can choose not to provide any data about themselves and still continue reading the article. Those who do not offer such options to users may face regulatory sanctions.
Consent Mode 2.0, along with the rules it is based on, extends to the European Economic Area, which Ukraine does not belong to at the time of writing this article. However, since many Ukrainian businesses operate for export or plan to enter the European market, it is advisable for all of us to understand this.
Impact on Marketers
User privacy protection ultimately means less data about potential remarketing audiences and advertising in general. Data from individuals who opt out of information collection should not be transmitted to Google Analytics or other systems. Accordingly, it is necessary to update the system to meet current requirements and keep abreast of developments regarding cookie opt-outs and transitions to new tracking methods.
Previously, we discussed the importance of user privacy auditing in the article “Website Privacy Audit.”
Technical Changes
Google Analytics now includes two mandatory parameters:
- ad_user_data —permission to transmit data related to Google advertising (ads, dv, etc.)
- ad_personalization — permission for personalized advertising
These new parameters must be considered in consent-gathering banners and event-processing tags. This should allow users to more accurately control which data they provide and how it is used for advertising purposes.
What to Do About It
If you have a website targeting countries in the European Economic Area (list), conduct a web analytics audit and adjust consent collection banners according to the new rules, with the “ad_user_data” and “ad_personalization” parameters.
If you use a Google-certified consent management platform, everything should update automatically. For guidance, refer to the help documentation or contact a web analytics specialist (e.g., newage.agency at info@newage.agency).
FAQ: Frequently Asked Questions About Consent Mode v2
What is Consent Mode v2?
Consent Mode v2 is Google’s updated consent framework that helps manage how user data is sent to analytics and advertising systems based on whether users have granted consent.
What new parameters were introduced with Consent Mode v2?
The update introduced the ad_user_data and ad_personalization parameters. The first controls whether advertising-related user data can be sent to Google services, while the second determines whether data can be used for personalized advertising.

It is primarily required for websites that serve users in the European Economic Area and use Google Analytics, Google Ads, or other Google advertising services.
What happens if a user does not give consent?
In this case, the website should not send personal data for analytics or advertising beyond the scope of the user’s consent. This may reduce the amount of data available for remarketing, personalization, and conversion measurement.
How do you implement Consent Mode v2 on a website?
You need to configure a consent banner, add the required consent parameters to your tags, and verify that consent signals are being transmitted correctly. If the website uses a Google-certified consent management platform (CMP), some settings may be updated automatically.
