What part I don't get is the following:
1. Are CPA networks basically the same thing as Commission Junction, Share a Sale, Google Affiliates, where you get a small commission on closed sales--effectively works out to a range based on $$$ earned per 100 clicks? or is there something I'm missing here.
2. I have a number of high traffic sites that a running cpm ads (not doing as well as I would like), are CPA banner ads any good? Any you would recommend for the health and fitness niche in terms of cpa network / product?
