Tried pop-under traffic included adsense on my site - no penalties from Google. Traffic is delivered as it is written in the service, so everything is ok
Great, will wait for your feedback
So, the traffic seems to give some positive results? This is great. What else can you do with it? Does anyone try it with CPAs? You know "leave your name and mail here and you will be part of a competition...". I thinks that this will work good.
