Flat rate advertising buys are purchases that are fixed in price for a certain period of time like a day, week, month, year and so on. For example, a flat rate traffic buy means that the price won’t change regardless of how much – or how little traffic you receive. Flat rate advertisement purchases are typically reserved for the biggest media buyers out there. Many great ad spots that provide high volumes of traffic sell at a fixed monthly price. Always remember, when dealing with flat rates, you need to pay the right price, and that requires a very accurate evaluation so you know what you’re getting in return. Happy bidding and good luck!
