Programmatic delivery channels

The following table defines the delivery channels that can potentially serve for the request you are inspecting.  These channels represent the sources through which you can monetize this set of inventory.

Note that for the channels denoted as “Open Auction,” only one channel needs to be eligible to serve. Ad Manager will show only the delivery channel(s) that were used for the request, even if other channels were technically eligible.

Open Auction: Line item  In this context, the line item refers to inventory you’ve made available to buyers on the open auction by allowing Ad Exchange or AdSense line item types to serve to those buyers specifically.
