Cross Domain Affiliate Tracking

Issue with Cross-Domain Affiliate Tracking Across Multiple Marketing Sites and a Store Site

Cross-domain affiliate tracking is not working properly when multiple marketing sites redirect traffic to a central store site for checkout. Let me explain this with an example:

• Site1: The main store site used exclusively for checkout and account management.
• Site2, Site3, Site4: Marketing sites that promote products and deals.

We have implemented a cross-domain tracking plugin on all three marketing sites (Site2, Site3, Site4) and connected it with the main store site (Site1).

Here’s the scenario:

1. Black Friday Page on Site2: A dedicated Black Friday deals page is created on Site2. This page lists not only Site2’s own products but also products from Site3 and Site4.
2. Affiliate Promotion: An affiliate promotes the Black Friday deals page on Site2 using their affiliate link.
3. Visitor Behavior:
   • If the visitor clicks a product listed on Site2 and goes directly to the checkout on Site1, the affiliate receives their commission correctly.
   • Problem: If the visitor first navigates from Site2 to Site3 (e.g., clicks on a product listed from Site3), and then proceeds to checkout on Site1, the affiliate does not receive their commission.

This issue arises because the affiliate tracking is breaking when the visitor’s journey includes multiple marketing sites (e.g., Site2 → Site3 → Site1). The tracking plugin fails to carry over the affiliate information across all domains involved.

This needs a solution to ensure affiliate data persists through the entire journey, regardless of how many marketing sites are involved before checkout on the store site.
