What is cross-domain consent?

Cross-domain consent is a type of consent that maintain users’ consent preferences as they navigate through multiple domains. This means that when a user visits a website for the first time, they will see a consent banner. Once they have made their choice, subsequent visits to other linked domains will not display any further banners to the user.

This feature can be enabled by using third-party cookies on all linked domains, which will recognize the user’s consent choice across these sites. However, it is important to note that Safari does not allow the sharing of third-party cookies across multiple domains if the users have enabled the “Prevent cross-site tracking” option. Moreover, Google Chrome plans to terminate its support for third-party cookies by 2024, making cross-domain consent sharing impossible there.
