I finally got my account with Yahoo Publisher Network going. Got the code to put on my website and inserted it where i have my google ads now (Took google ads off and replaced them with YPN ads) Well after putting the YPN ad's up there is nothing there.. solid white where the ads are supposed to be. finally got fed up with it after trying and trying and put adsense back up. Anyone have of had this problem?
This is the same thing that happens with G. You need to wait for YPN to find suitable ads for your site. They don't just appear the first 30 seconds that you paste your code in the file. BE PATIENT
