How to enable cross-domain cookie consent?

Cross-domain cookie consent is used when you want to collect cookie consent across multiple domains using a single cookie banner. This feature is useful when you redirect users to multiple websites or domains and helps to increase the user experience.

You can create a group of websites, which will share the same cookie banner and cookie consent for all domains.

When you configure your cookie banner for the group, all websites in the group will have the same settings of the cookie banner. For example, if you configure the cookie banner with the granular choice of cookies, all websites in the group will have the same granular choice of cookies.

Similarly, cookie consent, once selected by a user, will also be the same for all websites in the group. If the user selects "Accept All", this choice will be valid for all websites in the group. If the user later revokes their cookie consent, it will be valid for all websites as well.

You can add any websites (subdomains or different domains) in the group, if they use the same cookies or other tracking technologies.

To enable cross-domain cookie consent, perform the following steps:

  1. Go to your CookieScript user dashboard, where you will find the option Cross Domain settings.

  2. Create a group of websites for cross-domain consent by pressing the tab Add group:

  3. Add a website by selecting an item from the drop-down list:

  4. Add all websites, where you want to activate the cross-domain feature and click Save:

 All done, you have enabled cross-domain cookie consent for several domains.

You can also create several groups of websites that will have different cross-domain cookie consent.

Note: In order for the cross-domain cookie consent should be valid, you should use the same cookies or other tracking technologies on all websites in the group, where your cross-domain cookie consent is activated.

Note: Even if you group several websites for common cross-domain cookie consent, it may not necessarily be activated. There are conditions for cross-domain cookie consent, that must be met from a user side or related to browser settings.

Conditions for cross-domain cookie consent from a user side

Even if you group several websites for common cross-domain cookie consent, it may not necessarily be activated. There are conditions that must be met from the user side:

  1. The user should accept third-party cookies.

  2. The user should not activate “Do Not Track (DNT)” in their browser settings.

  3. The user should accept cookies in the “Preferences” category since the cross-domain cookie consent sharing local storage item is classified as a preference cookie.

Browser-related restrictions, related to third-party cookies

Cross-domain cookie consent sharing will not work for some browsers that do not allow third-party cookies by default.

  • Safari: Cross-domain cookie consent will not work with Safari, since the browser does not share third-party local cookie storage across different browser tabs.

  • Mozilla Firefox: Cross-domain cookie consent will not work with Firefox, since the option to block cross-site cookies in all windows is set by default. When the option “Delete Cookies” is enabled, the feature will not work with Firefox as well, since the browser clears all cookies for every new tab automatically, which prevents saving consent.

  • iOS browsers and iOS devices: Most Apple browsers use their built-in WebKit, the web browser engine, which automatically blocks third-party cookies, so cross-domain cookie consent will not work with them as well.
