what do you think is the best converting CPA program/advertiser/ad you see on CJ, Google Referrals, CB or whoever we know ? What is a campaign which makes people sign-up like crazy and at the same times pays out well ? Maybe adult stuff like AFF (free signups ??) ??? I always think it must be something free, no obligation-BS so people CLICK on it. What experience do you have with certain campaigns/specific ads and advertisers...how well do they convert ? Or just do some more keyword-research, find some good keywords and then look for an advertiser ?
I don't think you would get much of an answer for this. The reasons for this is because the person that would tell you would most probably be the person doing it already with that offer and it will only create much more competition for him/her.
I can tell you that credit cards through Credit-Land.com convert well especially if you have good traffic. They typically are free to sign up for. Many have no annual fees so it is much easier to get someone to apply for a credit card than to sell tem a product. The commissions are good anywhere up to $90+. See my sig if you want to apply. There are many other profitable fields as well.
