Polyhedron is a programmatic “bidder”: it reshapes and adapts a campaign targeting scheme 24/7 in order to best fit a campaign’s needs and features of the currently available inventory (both managed and third-party).
Usually a campaign manager chooses the campaign targets at the very beginning then checks delivery progress and performance level daily, possibly inserting and removing audience segments, geographic areas and so on. The target selection is intuitive, at best based on experience with past campaigns. Polyhedron algorithms perform target reshaping using campaign feedback data in a way which would be absolutely unfeasible for human users.
A groundbreaking feature of Polyhedron is multi-dimensionality. It simultaneously selects audience segments, pages, geos, devices, browsers, operating systems, day-parts. This amounts to evaluating thousands or even millions of multi-targeting options, a colossal task made manageable only by sophisticated proprietary algorithms. To the best of our knowledge, no other tool offers this kind of service.
