Private inventory can be purchased by targeting private deals in your line items' inventory source targeting.
Follow these best practices when purchasing private inventory:
- Your line item's bid must meet your private deals' CPM price floor (also known as "minimum bid") in order to purchase impressions. If you bid higher than this, you'll still only pay the floor price, even though other, regular public exchange auctions in Display & Video 360 are second-price auctions.
- If a line item targets only private inventory (non-guaranteed fixed deals or non-guaranteed auctions), we suggest you disable vCPM for that line item.
- Each line item should target a single deal.
