What ive been doing to test new creatives is cloning the existing campaign and running the cloned campaign with the winning creatives, while pausing the winning creatives in the old one and running new creatives. Few questions:
1) Is this hurting my CTR with over exposure? Note I am not running the same creatives in 2 different campaigns
2) How do you test the same images with the different body copies? Do you run the 2 same images with different bodies at the same time?
1) You might get both of your campaigns served at the same time to the same user if they are the small ads. If you are fine with that, then it’s fine. I don’t do that though. If it’s IAB, then you’re essentially increasing your frequency cap by duplicating campaigns.
