You can use Promo Code Exception Lists to pay partners different rates (including $0) based on promo codes associated with actions they drove. You can also create exception lists based on item categories or SKUs.
Coupon Ads are simple text link ads that provide your partners with content to host and link to your promotions. Tracking Promo Codes, on the other hand, incorporate crediting logic—meaning that when a code is used, impact.com will assign credit to a partner, or away from a partner, depending on the click path and setup of the code. A coupon ad will fall back to the crediting logic of your program for clicks (which likely requires the partner to be the last click).
Regex stands for Regular Expression. It is a special string of text used to describe certain patterns using wildcards. Regex can be used to assign dozens of codes that all begin with the same prefix to a partner.
Example: If all your codes begin with SUMMER but end with other characters, you can set up the code with the Regex ^(SUMMER).* to capture any promo code beginning with SUMMER.
The code will not expire and will remain assigned to that partner. This means any sale attributed to the code and partner, after a partner contract is expired, will be reported in the Invalid Conversions Report.
Promo code tracking needs to be enabled for your program before the option will appear.
