YieldLift is an advertising exchange, a web-based service that enables websites, apps and advertisers to market, sell and buy digital ad space. YieldLift helps demand side platforms, advertising agencies and brands (“Demand Partners”) buy digital ad space and helps ad networks, website and app publishers (“Publishers”) generate revenue by selling available ad space. The decision to sell or purchase ad space between Publishers and Demand Partners happens through an automated, software-based process called "real-time bidding" where multiple advertisers bid on places to show their ads.
