OpenX market provides an independent marketplace for the publishers. Publishers can connect to advertisers directly to sell their inventory. OpenX market runs a real-time auction for each ad impression, with advertisers doing the bidding. In that publishers can define a minimum floor price for their ad impressions. If the winning bid from the auction is higher than the publisher set minimum price, then the ad will be displayed from the winning bid campaign. If the winning bid from the auction is less, the publisher’s original ads will be displayed.
