I guess you could say it's working for me, I have made 29 sales in the last 27days. I'm sure there are many that make much more than that, but I am happy with my results. Clint
Its possible to make good money with CJ, but ensure that you dont be stupid, i.e put a $100 commission product thinking that you will make more that a $1 product people are more likely to buy, so in the end you make more money from more smaller sales.
Yes CJ does work for publishers. It takes more than just displaying ads though. You have to match the right ads to the right website/content and then get the right traffic to visit that site. For example, there's no point showing steakhouse vouchers on a vegetarian website - if you did you could get 10,000 page impressions but you wouldn't make a penny probably!
Its lie anything - a product and interested people result in sales. CJ is great if you are getting targetted traffic suitable to your affiliate banners. Free adwords and cj works well though!!
