Marketplace Auction Dynamics

MoPub Marketplace operates on a first-price auction.

The time limit to respond to a bid request and be considered for the auction is 1000ms for the unified auction and 300ms for Marketplace line items. We expect all publishers to migrate to the unified auction in the future, but timeout values will vary until this work is completed.

All applications in the MoPub Marketplace pass a price floor via the bidfloor parameter in the bid request. Publishers work with MoPub teams to determine the price floor, based on a variety of factors.
