Question: An advertiser is participating in a bidding environment where a publisher has established a floor price and restricted the auction to a select group of invited participants. Which transaction type are they using?
- Open auction
- Private auction
- Inventory package
- Preferred Deal
Explanation
This setup matches a private auction, which Display & Video 360 defines as a non-guaranteed auction where the seller invites specific buyers to participate. The publisher can require bids to clear a minimum CPM, so the floor price is part of the transaction mechanics. The highest eligible bid wins only if it is above that floor. That combination of invited access and a publisher-set floor is the defining pattern of a private auction. Google Help
Why the other options are incorrect
Open auction is broader marketplace inventory rather than seller-invited buying, so it does not match restricted participation. Google Help
Inventory package is a collection of non-guaranteed inventory available to all buyers on Display & Video 360, not an invited-buyer auction type. Google Help
Preferred Deal is a non-guaranteed fixed deal with fixed CPM and first-look access, not an auction where invited buyers compete above a floor. Google Help
