What is subdomain consent?

Subdomain consent is a feature that helps websites collect user consent across subdomains using a single cookie banner. User consent is shared across all the subdomains of a main domain. This means when a site visitor goes from one subdomain to another, they will be recognized as the same visitor and not shown a banner each time. This feature helps websites to improve their user experience when they have multiple subdomains.

CookieYes allows websites to implement subdomain consent. For instance, if you install CookieYes on your primary domain (www.example.com), all subdomains (help.example.com) will have access to the same consent information.
