DSP
In plain English
What does DSP mean?
Demand-side platform: software that lets advertisers bid on ad impressions across many exchanges and networks from one interface.
A DSP aggregates inventory from ad exchanges and applies targeting, bidding and optimisation. Self-serve DSPs open programmatic buying to affiliates who used to rely on individual networks. Minimum spends and learning curves are higher; reach and control are greater.
