Ill be honest, I cannot figure out how to bid or optimize a campaign to profit bidding manual CPM. What is wrong with me? If I use a traffic source with some sort of machine bidding I am ok. But, I feel trapped. I learned with a traffic source that bids the CPM for me and it has become a crutch.
Can some one give me some pointers on manual CPM optimization? I have tried multiple manual CPM sources and have never done better than negative 80-90% ROI. That is how bad I suck. This is with proven camps from my machine CPM bidding source where I make money. The moral here, I cant even make money on winning camps using manual CPM. If I could, the World would open up to me.
