determining, for each of a plurality of content bids, a characteristic of a content campaign associated with the content bid; conducting, using a computerized auction system, at least one first auction process to select a first set of one or more winning content bids from among the plurality of content bids based in part on a first eligibility constraint, wherein each of the plurality of content bids comprises a bid to include a content item associated with the content campaign within a content interface, wherein the content interface comprises a plurality of positions in which content items can be displayed, and wherein the first eligibility constraint comprises a limitation on the number of winning bids that share a particular characteristic; determining, using the auction system, whether a number of winning content bids within the first set of one or more winning content bids selected using the at least one first auction process is less than a number of positions within the content interface; when the number of winning content bids within the first set of one or more winning content bids is less than a number of positions within the content interface, conducting, using the auction system, at least one second auction process to select a second set of one or more winning content bids by either disabling the first eligibility constraint or applying a second eligibility constraint to the plurality of content bids instead of the first eligibility constraint, wherein the second eligibility constraint permits a larger number of winning content bids to share the particular characteristic than are permitted under the first eligibility constraint; generating, using the auction system, the content interface based on at least one of the first set of one or more winning content bids or the second set of one or more winning content bids; and transmitting, using the auction system, data representative of the generated content interface to a computing device of a user; wherein the operations of conducting at least one first auction process, determining whether a number of winning content bids within the first set of one or more winning content bids selected using the at least one first auction process is less than a number of positions within the content interface, conducting at least one second auction process, generating the content interface, and transmitting data representative of the generated content interface are all performed in response to a single request to provide content items for the content interface. |
