Google Adsense and YPN (Yahoo Publisher Network) Ads Rotated by Country I have never liked using IP addresses to sort ads mainly because of the wasted space (Not to mention the Countless people using Proxy's) So I created a simple script to rotate my ads Based on Language and Country. By now anyone using YPN (Yahoo Publisher Network) knows they only pay for US Traffic - and you can lose a good bit of income by using their ads alone.
