Well I thought I would just dip my toes in the water a bit here. I found a decent product and sales page of CB. I went to buysellads.com and found a site that fits the same niche. I purchased the main 300x250 spot. at $1 per 1000 impressions. I am doing a split testing with two images. One image is a (sitename special) and the other one is just a regular ad which the CB seller supplied. I only purchased 20,000 impressions each. Like I said I am only dipping my toes in this just to see what happens. I dont mind blowing the $40 if that ends up happening. The CB product has a really nice payout $35 per sale with a refund rate of .22% Ill post all my numbers, charts etc once its over. Wish me luck!
