Some advertisers will pass unique sub ids to provide additional information about a particular click (such as the creatives used or traffic source). This information can be stored in Red Shell using affiliate sub ids. Passing affiliate sub ids to Red Shell allows you to generate reports with more detail since you can break down your stats by sub id. These parameters (
aff_sub2, aff_sub3, aff_sub4, aff_sub5) can be appended to any of our tracking links.
aff_sub is reserved for passing transaction ids and isn't included in our reporting. Please use
aff_sub5 if you would like to be able to report on these values.
