I want to advertisie with Google PPC Managment. But I`m really cofused about Bidding System. Actually I want to show Image Display ads with Google Parthners. I have no idea about CPC Rate. That is why, i can`t start my campagin. Can anybody tell me if i open a new campagin with Google Display Ads (300x600 size),then what should be my bidding rate. Only $300 Budget for Current Month. N.B: I want to advertise for my BIZ Wordpress Theme. Thats mean, I`m going to work with "Premium WordPress Theme" Keyword (something like that). It`s too much high comptition. Advance Thanks.
