Open auctions are where many advertisers compete at the same time for ad space, usually through real-time bidding. These are open to anyone using the ad platform, and the highest bid wins. Private marketplaces are more controlled. Publishers invite selected advertisers to bid, often with better-quality placements or websites. While open auctions may give wider reach, private marketplaces can offer better traffic and more control over where ads appear. This can help reduce wasted spend and improve brand safety. Each one has its benefits depending on the goal of the campaign. Has anyone compared the results from using both types before?
What’s the difference between open auctions and private marketplaces?
