I really wish there was more of a variety of advertisers on YPN. I ran YPN on one of my sites for a month, then switched to Adsense... YPN pays more than twice as much for the same amount of clicks as Adsense does, but I see the same ads over and over. But since YPN was making me more money, I've switched back. Hopefully, in time, the pool of advertisers will grow.
Exactly, either that, or it's becuase the payouts are high, which means advertisers are being chraged high prices... for less traffic? Why would you use YPN instead of Adwords if you were a advertisers... I know i wouldn't
