Adversal pays you per page view. The rate is $1.20 per 1000 US page views and $.50 per 1000 non US pages views.

Basically adversal is a pop-under system but it is pretty unobtrusive. If you have decent traffic, you can earn a little bit here. Internal links can’t be blocked by popup blockers so you can still earn even if they have them.

Simply sign up and place the code in your site. The more pages you place the code on the more money you make.
