I'm pretty new to all of this. But anyways I just started an AdWords Campaign, promoting a couple of ClickBank Products directly through my affilate link (without a landing page). I was using the CPM pricing model, bidding about $1.00 per thousand impressions on a $5.00 a day budget. I had to pause the campaign after 2 days because it showed around 70,000 impressions for both ad groups with only 10 clicks and costed around $50 but they didn't charge it. However, I got lucky and made a $40 sale off of the 10 clicks. I am only using the targeted content network with about 30 targeted sites. All 4 of my ads appear well relevant. Am I doing something wrong? Should I use CPC, bidding and keywords?
