I have an auction site that doesn't work in the normal way. The price goes down everytime someone someone clicks on the "View Price" button. To view the price of an item, the user purchases credits. Each credit costs 50cents. Why would someone pay 50 cents to see the price of an item go down only 25cents? there are sometimes hundreds of people clicking on the "View Price" button at the same time. If you are the 573rd person to click on the view price button, you would see a price that is exactly $143.25 less than the original price. (573 x .25 = $143.25) As you can see, this is easy, but complicated I'm having limited success getting the word out and people are bidding the price down but i don't know in a marketing sense how to explain the process briefly for PPC advertising. PPC seems like its the best way to "Get the Message Out", but it doesn't leave enough room (text) to really get it done. Any Ideas? please PM me if you have some thoughts. I'm not listing the site here because I really would like some ideas and don't want to be listed for spam.
