The value of a mobile demand side platform (DSP) lies in its transparency. Mobile DSPs allow you to buy mobile ad inventory, across a range of publishers, through a single platform. You can see the market rate for every impression you buy, control which exchanges you want to buy across and how much you want to bid. Mobile DSPs are designed to tackle the many challenges of mobile advertising, including targeting and the need for a positive user experience. Recent advances in technology mean that mobile DSPs can now track models, operating systems, screen size, location and more.
