Embodiments of the present invention relate to facilitating control of advertisement spending. In embodiments, a spend rate allocated to a datacenter having a plurality of bidders is referenced. The spend rate allocated to the data center is used to determine a spend rate per bidder for each of the plurality of bidders within the datacenter. For each bidder, the spend rate per bidder is used to generate a bid rate indicating a number of advertisement bids to place per unit of time in accordance with a real time advertisement auction. Each bid rate generated for the corresponding bidder is intended to result in placement of an amount of advertisement bids that correspond with the spend rate per bidder. The bid rates are provided to the plurality of bidders, wherein each of the plurality of bidders uses the corresponding bid rate to determine whether to place a bid for an advertisement.
