Does Commision Junction Affiliate Work For You?

Today as I was talking with a friend who recently got started with internet marketing, she told me that she started with Commision Junction (CJ) and she hardly makes any sales. While, I am doing IM for a few years, I have yet to make good money with CJ.

I do better with Amazon (not this site) and adsense (again not this site) but I use CJ primarily with this site except for a few exception but my CJ affiliate income is nothing to write home about. I think 1 to 3% is return on affiliate is reasonable but it is not the case with CJ. So, I could not tell my friend what to do to improve the percentage as I am stumped myself. I have called CJ and vendors without much help.

Very few people I know who are in IM are in same boat as my friend or have crazy traffic in order for them to work. Do you work with CJ? Are you getting good earning from it? How to improve your affiliates from it?

I am curious for those of you who are good at earning from CJ, do you have any recommendation on how to work best with Commision Junction Affiliates?
