I noticed in my CJ account last night that they just launched something called the Cross-Account Correlation pilot program.
Cross-Account Correlation enables affiliates to receive commissions for referrals across an advertiser’s entire enterprise, even if the merchant operates multiple web sites and multiple affiliate programs.
Also, affiliates can view which of their commissionable actions resulted from Cross-Account Correlation, and adjust their campaigns accordingly.
Cross-Account Correlation is currently available to all affiliates who have an active relationship with a merchant participating in the pilot program.
