This essentially means that in newer versions of the Chromium browsers it is now only possible to share consent between domains that share the same top-level domain. This means that consent submitted on a sub-domain can be shared with other sub-domains and the top-level domain, but not the other way around.
Consent submitted on the top-level domain can not be shared with a sub-domain.
If you operate multiple websites from different domains or your website operates from several subdomains, Cookiebot CMP can ask your website visitors for a consent that applies to all domains within the same Domain Group. We refer to this as Cross-domain Consent Sharing.
By default, your users will be asked for consent on each of your domains separately. By enabling the Cross-domain Consent Sharing feature however, your users will only be prompted for a consent the first time they visit any one of the websites in the Domain Group (and again when consent has expired).
How does Cross-domain Consent Sharing work?
When Cross-domain Consent Sharing is enabled, a local storage item named CookieConsentBulkSetting-# is set to keep track of users' changes and renewal of Cross-domain Consent Sharing across domains. This third-party Local Storage item contains an array of domains within the domain group. Upon visit to one of these domains after the initial consent submission the entry is popped from the array and the consent settings from the domain where the user submitted consent are applied to the domain.
Does Cross-domain Consent Sharing work for all website users?
In order for the Cross-domain Consent Sharing to function properly, these following three conditions must be met:
- The user allows third-party local storage in their browser settings. Browsers like Safari and Firefox are known not to allow third-party cookies by default.
- The user has not activated “Do Not Track (DNT)” in their browser settings
- The user accepts cookies in the 'Preferences' category. The Cross-domain Consent Sharing local storage item is classified as a preference cookie, so if this category isn't accepted Cross-domain Consent Sharing can't carry over.
Activating Cross-domain Consent Sharing
Activating Cross-domain Consent Sharing is as easy as ticking a checkbox in your Domain Group configuration:
- Log in to your account: Cookiebot CMP Manager
- Go to ‘Settings’ from the top menu
- From the drop-down menu just below the top menu, choose the Domain Group for which you wish to enable Cross-domain Consent Sharing
- Click the ‘Domains‘ tab
- Check the checkbox labeled ‘Enable Cross-domain Consent Sharing’
- Save your settings by clicking the tick mark on the left-hand side in the blue bar.
- Log into the Admin Interface.
- Select "Domains & aliases" from the left-hand menu.
- Click "Manage your domain groups"
- Click the ">" icon to the right on the Domain Group line you want to enable Cross-domain Consent Sharing for.
- Check the box under "Cross-domain Consent Sharing".
- Remember to click the "Save changes" button in the top right corner.
This also applies when withdrawing consent. By withdrawing consent, permission to carry over consent settings to third-party domains is also revoked.
