A campaign must be assigned to a zone or a channel (i.e. a group of zones) so you can serve the ad items in that campaign. It must have at least one ad item so that it can be assigned.

You can assign a campaign only to a zone of the corresponding type. Image and HTML/Rich media ad items need to be in a standard campaign and must be assigned to a standard ad zone. Email ad items need to be in a standard campaign and must be assigned to an email ad zone. Finally, VAST ad items need to be created in a VAST campaign and assigned to a VAST ad zone.

Similarly, remember that a channel is a group of zones. While AdButler will let you assign a campaign to any channel, the campaign will be selected to serve only if the channel to which it was assigned has a zone that is compatible with the campaign.

Assigning a campaign to a zone or a channel

1. Go to the section of the relevant campaign ( Your AdButler > Advertisers > Your Advertiser > Your Campaign ).
