“A demand-side platform (DSP) is a system that allows buyers of digital advertising inventory to manage multiple ad exchange and data exchange accounts through one interface. Real-time bidding for displaying online ads takes place within the ad exchanges, and by utilising a DSP, marketers can manage their bids for the banners and the pricing for the data that they are layering on to target their audiences. Much like Paid Search, using DSPs allows users to optimise based on set Key Performance Indicators such as effective Cost per Click (eCPC), and effective Cost per Action (eCPA).”
