If i was to promote your website as an affiliate, I would personally be turned off by the adsense, because it would hurt my potential for making a sale with your site. ...but if you have adsense inside the membes area...
ya i definitely to NOT recommend adsense on a clickbank website, i mean sure you might get a whopping $.25 for a click but it very likely could have taken a customer away from a potential $xx sale.
I use Clickbank and adsense, and I make more money with clickbank. If someone doesn't want to buy, he can click on my ads, and still give me money. If he want to buy, even if he clicks on the adsense ad, he will come back. But to say that you got to remove adsense. You must splittest, and see what happens after 2 or 3 months.
I put it in my site not on the main sales page You do not want to distract the potential buyer and hack off your affiliates. One final thought you will in effectbe advertising competitors ... John Vaux
