I got a email from YPN,

Due to the quality of the leads generated from your sites, we have disabled the use of Ad Targeting for your account. You may continue to display contextually-matched ads that Yahoo! serves, however, the matching suggestions provided by the use of Ad Targeting will not be utilized.

Well, YPN Never target for my sites, that’s why lead is poor. They never did good job on targeting like Big G. Now they telling me my lead is not good. Well, no wonder YPN is still in Beta stage.

So, what now? My avg RPC(Rate per Click) is dropped from $.55 to $.15. $.15 per click is not bad compare to other contextual programs, but YPN ads still has much lower CTR than Adsense which I am testing other contextual programs.
