Google Consent Mode V1
The first version of Google Consent Mode was launched in 2020 to help protect user privacy. This was driven by the introduction of data privacy laws such as GDPR and the ePrivacy Directive.
This version of Google Consent Mode meant that Google was still able to capture data for Google Analytics and Google Ads platforms.
With V1, there were two consent states: analytics_storage and ad_storage. These respectively asked a user if they consented to their data being used for analytics and advertising.
However, a change has been deemed necessary following the introduction of a new EU regulation. The Digital Markets Act (DMA) was first launched in November 2022, with the aim of preventing large companies such as Google abusing the power they hold in the digital market and ensuring a higher degree of competition across all European digital markets.
A similar act - the Digital Markets, Competition and Consumers Bill (DMCC), has also be introduced in the UK specifically.
The major industry players have until 6 March 2024 to comply with the provisions the DMA lay out, hence the introduction of Google Consent Mode V2.
Introducing Google Consent Mode V2
As part of the new version of Google Cookie Consent Mode, two new consent variables are being added: ad_user_data and ad_personalization.
Depending on whether a user gives consent or not, ad_user_data determines whether personal data is sent to Google, be this via Google Ads, Google Shopping or Google Play.
Based on whether consent is given by the user, the ad_personalisation consent variable also, determines if personal data is sent to Google for remarketing purposes.
These new consent states are in addition to the consent states that feature in Google Cookie Consent Mode V1, meaning Google Cookie Consent Mode V2 will have four consent states:
- analytics_storage
- ad_storage
- ad_user_data
- ad_personalization
Moving forward, the behaviour of Analytics and Google Ads Conversion Tags fired will rely on these four variables.
This means that if a website does not give defined consent, advertisers will be prevented from tracking data for users in the UK, EEA and the US.
What you need to do
To help manage the transition to Google Cookie Consent Mode V2, Google has launched Advanced Consent Mode. This helps websites get their analytics, tags, tracking and cookie management set up for Google Cookie Consent Mode V2. This way, website managers can ensure they receive the consent they need to send data, while also ensuring data is fully anonymised when consent is not given.
We recommend moving to a compliant consent management platform while Google Tags are updated to become compliant.
Our recommended platform for this is Cookiebot, as this will preserve all your Google Analytics and Google Ads tags when the consent rollouts take place. Cookiebot will also recover some of your lost data when consent is denied.
Additionally, Cookiebot will automatically track and control all other scripts on your site, as well as avoiding any compliance risks you may not be aware of.
Google Tag Manager is quick and easy to implement, offering full consent V2 capabilities, but doesn’t touch the other manually installed scripts on site. As a result, we recommend a hybrid method to track all scripts.
