Cross-Domain Consent Sharing - Consentik Wix

Cross-Domain Consent Sharing allows your visitors to consent once across all of your websites — no repeated banners. If a visitor has already made their consent choice on one of your sites, any other site in your configured group will automatically recognize and apply that same decision silently.

This means a smoother, less intrusive experience for your visitors, and a consistent consent record across your entire brand presence.

Note: This feature is available on the Unlimited plan only.

Who Is This For?

This feature is ideal for merchants who operate:

• Multiple subdomains of the same root domain (e.g., shop.mystore.com, blog.mystore.com, support.mystore.com)
• Multiple separate custom domains for the same brand (e.g., mystore.com, mystore.eu, mystore.co.uk)

How It Works

Once enabled and configured, here is what happens when a visitor lands on one of your sites:

1. First visit — The visitor sees your consent banner as usual and makes their choice (accept or decline).
2. Next visit to another site in your group — The visitor's previous consent is recognized automatically. No banner is shown again.
3. Consent update — If the visitor updates their preferences on any site in the group, the new choice is applied across all sites on their next visit.

Visitors are informed about cross-domain sharing directly in the consent banner on their first visit, as required by GDPR. For example:

Your consent will be shared across: mystore.com, mystore.eu, mystore.co.uk

Setting It Up

Go to Settings → Cross-Domain Consent Sharing in your Consentik dashboard.

Step 1 — Choose Your Sharing Scope

You have two options:

Step 2 — Copy Your Configuration to Other Sites

Each site in your group must have Consentik installed and configured with the exact same domain list. Use the clipboard button next to the domain field to copy your configuration and paste it into your other stores — no retyping needed.

Step 3 — Save and Enable

Save your settings. The feature is now active. Repeat the same configuration on each site in your group.

Important Notes

• All sites must use the same domain list. If even one site has a slightly different list, cross-domain sharing will not work for that site and the consent banner will appear again.
• Changing your domain list resets sharing. If you add, remove, or edit any domain in the list, visitors will see the consent banner again on their next visit. Their existing consent records are not deleted, but they will not be recognized under the new configuration.
• Consent is browser and device specific. A visitor who consented on their desktop will still see the banner on their mobile device, as consent is stored in the browser.

Frequently Asked Questions

What happens if I change my domain list?

The consent group is identified by your exact domain list. Changing it means sites can no longer find each other's consent records — visitors will see the banner again as if for the first time. Their existing records in your consent log are not deleted.

What if a visitor revokes consent on one site while browsing another?

Revocation takes effect on the next page load. If a visitor revokes consent on Site A while Site B is open in another tab, Site B continues operating under the previous consent for the remainder of that browsing session.

Does this work on all browsers?

Cross-Domain Consent Sharing works on Chrome, Firefox, and Edge. Safari users may not benefit from this feature because Safari blocks the type of cross-origin cookies this feature relies on by default. Safari visitors will see the consent banner on each site independently.

What if the cross-domain hub is temporarily unavailable?

If the system cannot establish cross-domain communication within 2 seconds (e.g., due to network issues or a browser extension blocking it), Consentik automatically falls back to showing the standard consent banner. This ensures your site remains GDPR-compliant at all times.

Does this work with TCF (IAB Transparency & Consent Framework) banners?

Yes. If all sites in your group use TCF banners with the same vendor configuration, consent is fully shared including the IAB TC string. If you have a mix of standard and TCF sites, visitors coming from a TCF site to a standard site will have their consent recognized. However, a visitor coming from a standard site to a TCF site will still see the TCF banner.
