What is Consent Mode v2?
Consent Mode v2 (CMv2) is the updated mechanism by Google that allows businesses to adjust the functionality of Google tags based on user consent for ads and analytics cookies. This ensures that tracking for advertising campaigns occurs only with user consent, as signalled through CMv2.
CMv2 processes the consent preferences of your users obtained through your consent pop-up. It adjusts the functioning of Analytics, Ads, and third-party tags responsible for creating or accessing cookies based on these preferences.
In cases where visitors decline consent, instead of saving cookies, tags transmit signals to Google. For users using Google Analytics 4, Google compensates for the absence of data collection by utilising conversion modelling and behavioural modelling.
Basic vs Advanced Mode
There are two different modes available in this version: Basic and Advanced. Our solution can be used to implement either one.
Important! It is important to note that to continue to use Google Advertisement products after March 2024, you have to at least have the basic mode implemented. The advanced mode is optional.
In the basic consent mode implementation, no information from users is collected at all, not even consent status. However, in the advanced consent mode implementation, Google tags are loaded before users are presented with the consent pop-up and Google collects cookieless data that lack personal identifiers.
Benefits of Consent Mode v2
There are many benefits to utilising CMv2, here are just a few:
It enriches your conversion data through conversion modelling for the users who do not grant consent.
It helps advertisers recover some of the data lost when users reject cookies, improving the quality of the bidding algorithms and measurement capabilities.
It gives the ability to continue using Google Advertisement products including Google Ads past March 2024.
