If an advertiser is outbid in a private auction, the impressions are awarded to the advertiser who has placed the highest bid.
- The deal is automatically canceled for the advertiser.
- The advertiser automatically wins the auction.
- The advertiser still receives half the deal impressions.
- All deal impressions go to the advertiser with the highest bid.
The correct answer is: All deal impressions go to the advertiser with the highest bid
Explanation: In the context of Display & Video 360, when multiple advertisers participate in a private auction, the system prioritizes the highest bid for a given impression. If an advertiser’s bid isn’t the highest, they will not win the impression, and it will go to the competing advertiser with the highest bid. This competitive process ensures that the inventory is sold at the best possible price for the publisher while still offering advertisers the opportunity to bid for valuable ad placements. Open Auction optimization may also be in play, allowing bids from the open marketplace to compete with those from the private auction, further influencing the outcome of which bids win the available impressions.
