To me, i dont think there is any specific product that will guarantee six figure income, but the clue is just to promote only the products that are related to your website's content/feel.
I get the impression that if you want to be successful with CJ, you have to very specific about that keywords you use to promote their products. By this I mean, the more specific the keyword, the better your chances of converting, since you will also have less competition. Fore example "barbecue grills" has over 240K searches/month in Google, but "coleman barbecue grills" get 1,300 and "stainless barbecue grills" get 4,400 searches. Go for the more specific terms, and I'll bet you'll find fewer competing sites too.
I've made 3xx for the last 2 years but I just take a serious "action" on the last 9 months.. I have set my payment to 300 but there's no check sent yet.
I use to make very good money promoting CJ merchants. The key back then was to find a "hot" product that had little competition in the search engines and make a killing before the popularity died down. Now there's A LOT more competition in nearly every good niche. Still, I'm sure that with enough research it's possible to find some very profitable things to promote from CJ.
I have had great success with CJ's CPA offers. Amazing advertisers on CJ. Great support, and I like the contact advertiser feature they have, they'll often supply you with converting descriptions/pictures to help promote their products.
