You are able to assign up to three custom values to a partner. Once the custom values are assigned, you are then able to add the values to your landing page query string. Assigning custom values to your partner helps:
Identify the partner by name in your internal analytics dashboard.
Specify the type of traffic associated with the partner (e.g. paid search, email, loyalty, coupon, toolbar, etc.).
Track if you have worked with the partner through another network and want to be able to marry the data and assign the Partner ID from the other network.
Note: When you set a custom partner value, data will start populating based on the last date you updated the partner contract. When looking at historical data and to avoid confusion, only consider data collected after the partner value was implemented.
