My guess is that a pop-under exchange would be equally fruitless to everyone but the exchange who sells their split.
Personally, I'm starting to pay more attention to which sites I routinely visit that spam me with a pop-under and I'm retaliating by finding other sites to visit. I think the general surfing public will eventually get fed up enough with this form of spamming to do likewise.
I personally find the best way to get links is via research, and link affliate's are definetly on the down list. Certainly an area, certainly of the affiliates concerns, that is going to be a loser.
4crests, if someone is visiting your page, because the search engines rank it as relevant to their inputted search term, then why would you be interested in advertisements behind your page.
Hunt the links. Can't beat it.
