Pop-unders
Hey guys,
I did some searches before posting this, but it seems that there haven't been any recent posts. The ad world changes so much that even from just a year ago isn't so reliable anymore.
I have a tube site and I'm look a good pop-under. Who are you guys using and what CPM rate are they offering? Also, what are your thoughts on them?
Thanks, hope to get some info!
