I am wondering if you could help me with a question. Let's say you have a 160x600 that runs site wide. And let's say you're working with companies like Criteo and OpenX and you're setting a floor in DFP below which Adsense ads will serve. What Adsense data would you use to figure out where the optimal price floor should be? Would you look at the RPM for the Adsense ad? If so, do you need to convert it to CPM? And do you want the floor to be 10%, 15%, etc. above that? In short, what's the best method for establishing the price floor? Thanks for any help with this.
