About assignments
To serve a campaign or an ad item in AdButler, you need to assign it to a zone or a channel. While doing so, you must specify how your ads will be served. The assignment includes settings such as how frequently an ad should be served, when it should be stopped serving, what priority that ad receives against other ads, which audiences to target, and any financial statistics to include as impressions or clicks are recorded.
Ad Item Assignments
When you create an ad item directly inside a zone, you will immediately configure its assignment details. The details specified in an ad item assignment are applied exclusively to that ad item.
Campaign Assignments
When you create a campaign, you will first create ad items in the campaign, then assign the campaign to a zone or a channel. The assignment details will then apply to all ad item items in the campaign. This is what we recommend for most ad serving setups, because it lets you easily serve one or more ad items to different zones and even different publishers. This also lets you track and view the ad items' statistics as one group.
