If you’re a YPN publisher but are worried about having too much non US traffic (they don’t let YPN be used on sites with too many non US readers) then you might find a tip written by Erik helpful on Saving Your Yahoo Publisher Network (YPN) Account from being BANNED.
In it Erik outlines how to show YPN ads only to US traffic and serve AdSense ads to non US traffic using a WP plugin.
PS: I can’t see similar principles in this tutorial couldn’t be used for using Chitika ads (they don’t pay for Asian traffic at this point).
