Does anybody know of a site like adfly, adfocus, linkbucks etc. that allows geo targeting or some form of targeting?(niche targeting) (I live in the USA and I want to target USA) I have something that I would like to advertise and I just wanted to know what are some people's experiences with any of them before signing up and starting my campaign. Popunders that convert well could also work. I just wanted to see how well it converts. If it does well them it might be worth it to advertise it on adwords. Cheap CPM or CPV or interstitial advertising that is worthy to invest in. I would really appreciate your help guys. Thanks.
