Abstract: A bid optimization system optimizes bid amounts in bid records of an information providing or advertising campaigns. The system includes a detection engine for detecting (finding) rules from campaign data, including bid records, from the profit report data of the campaign data. The bid records are organized in a set, which is continuously being updated and revised for profitability, to create a new set of reordered of bid records, based on these detected rules. The detected rules are then applied to the new set of reordered bid records, to optimize the bid amounts of each bid record.
