How Much Does Traffic Cost?
The price of traffic in a RTB environment very dynamic. In a real-time auction where practically every impression is sold for a different price, the answer would be another question: “The price for which impression?”
There are many factors that play into the price of each impression, but ultimately prices are dictated by supply and demand. For example, if nobody wants to buy Brazilian traffic from msnbc.com, then the cost might effectively work out to $0.25 CPM (hypothetically). If everybody wants to buy US traffic on cnn.com during Christmas season, the effective price of traffic might end up being $10+ CPM (hypothetically).
