I have been using Google Referrals to advertise PCNOW, been doing great there. Looks like there is more content on CJ though. Should CJ convert at least as well as Adsense? What takes so long to get approved its been a couple of weeks? The approvals really irritate me about CJ.
Theoretically I think CJ should convert better than Adsense referrals if you're promoting the same product. Most of the CJ affiliate partners give you referral duration period, so that even if your visitors don't take actions to earn you commission right away after clicking the affiliate links, they can still come back later on and take actions in the future (within the duration period). This is not the case for Adsense referral. I've never promoted the same product through both adsense and cj at the same time, but strangely, I usually have a better luck with adsense than cj.
You should try CJ (make the ad look the same as it does right now on your site), but you could also try promoting the more popular GoToMyPC through CJ as well.
