I have a contract with ad network for 1 position on my site. They gave me creatives (script). But sometimes they don't show any comercial. The script is running, but it returns an empty iframe. iframe height is 0.
Still, the position is reserved and Adsense does not replace empty iframe.
I put order with Sponsor tag, third party creative, no labels.
Can I somehow, with DFP, menage this to maximize my profit? In other words, can I set up my position in a way that if creative does not have an ad to show ->show adsense instead.
