I've been trying to work out how to use DoubleClick but it is very complex. I'd like to have an ad spot that changes ad tag depending on the viewers location. I have 2 ad tags from Sovrn, one I'd like to show to viewers in USA, one I'd like to show to the rest of the world. How can I use DoubleClick to do this?
You have to create a line item, campaign, then target it to the placement / ad tag you would like it to run on. Then you apply your tags from Sovrn to the campaign / line item.
