Private marketplace
A curated or invitation path to inventory, usually via deal IDs. Not the open remnant auction our first tests buy.
A private marketplace (PMP) is inventory offered to a selected set of buyers, usually through deal IDs, sometimes with a floor or a package story. It is still programmatic. It is not "the open exchange." You target the deal. You do not spray remnant and hope a PMP appears.
Adprime Zero first tests run on open exchange. We have not published a judged PMP versus remnant flight on this product, so we will not invent a quality lift for PMPs. Our exchange account has historically run no deals. If you already have a deal, trafficking it is trader work.
A PMP is not an IVT certificate and not a reason to skip click-to-page-view. Measure the path you actually bought.
If you are choosing a first $20/day cell, you do not need a PMP to start. You need a matching landing page and a prepaid wallet.
