Abstract: An auction management system brokers, between a seller and a buyer, a discrete traffic block of an ad placement, and may comprise a traffic block definition tool providing workflows for obtaining traffic block parameters defining the discrete traffic block. The traffic block parameters may comprise: i) an identification of the ad placement; ii) a volume parameter defining the volume of traffic included in the discrete traffic block; iii) at least one duration parameter defining an active time period during which the volume of traffic included in the discrete traffic block is provided; and iv) an auction parameter defining an expiration time before which buyers submit offers to purchase the discrete traffic block. A listing search tool provides web pages displaying a listing of a plurality of listed discrete traffic blocks. Each listed discrete traffic block comprises a discrete traffic block with an expiration time that has not passed.
