Private Marketplace is a method of Programmatic Buying with various DSP platforms including Google DV360. Private Marketplace provides access to unique ADBRO inventory at a fixed CPM within a single Deal.
Private Marketplace offers more flexibility over Programmatic Guaranteed as it doesn't require buying out all available inventory and allows volumes increasing without Deal re-negotiation.
