Hi, I've recently heard of paid xml feeds which can be placed in the site just like google search box. and if someone uses the search box and gets a result, a click on those result may yield money. How the advertisers or feed provider pays per click? do they have any bidding system in place? or a default bid system. I am very curious to know. Last but not least, who all are providing these kind of paid xml feeds? may i know. Pls help.
