Hi, I've seen many (especially American) networks offer revenue of over $2 for a "cost per lead". (I noticed one wanted you to download a toolbar so I get how they'll make money.) I've also seen many UK competition sites offer £50 to win a car etc How are they making money? Are they selling the data...if so, to whom? Or can anyone explain to me how these sites actually work? Examples from paidoffers dot co dot uk includes; "Enter this price draw to win a car and get £50" "Take LOVEFiLM's Free 30 Day Trial For £70.00 " "Join OfferX, Potentially Win £15K Cash & Get £30.00 From Us Too! " ...I am clueless as to how this work and really interested to know more.
