I have used CPM style marketing in the past to market clickbank products with decent success. However, recently I have noticed that the sales just aren't there. Actually, after driving more than 500 targeted customers, I haven't seen a single conversion. Is this normal now, or is clickbank just slacking on reporting? I was really just wondering if anyone else is suddenly seeing $0.00 all the time from clickbank now, and if so, any other good digital products networks out there that you know of?
