Too often, working with a Demand-Side Platform (DSP) feels a bit like buying a car. There’s the price given for the car and then, typically unshared, the extra fees to be incurred. What’s shocking, and often underappreciated, is that those extra fees can cost more than the car. DSPs typically price their platform fees as a percentage of media. This is easy to understand and track. However, what’s not often understood are all the extra charges.
