Pop-Unders

How to create

[fashezee]

Can I create a pop-under?

Also, I setup my account originally as Adsense for Content; but our site it much more search oriented now.Should I change account?

With AdSense? No, you can't put AdSense on a pop-under. I advise you to read all the rules *very carefully*.

You don't need to change accounts.
