Real Time Bidding (RTB) definition
Real-time offer consisting of an offer request and a response to it. The offer request is triggered when a user visits a page. The request data (user location, browser history, website, device) is offered for sale through an SSP and an Ad Exchange. A DSP connected to this Ad Exchange responds to this offer with price and creative data (response to offer). The highest bid for the placement wins and the ad is served. All of this happens automatically and in milliseconds.
