The Average Course Per Sale

Lately i've been doing auto targeting, so assessment is more do more assessment an optimization in those. I decide if it's doing well enough and how much room i have to work with. If it's not converting, sometimes ill just pull the plug. They're not every add is going to succeed. But generally speaking, my main thing is just determining how much i'm actually spending per sale,. And calebrating my expectations and my budget according to that.
