Use of natural query events to improve online advertising campaigns

A system and method to identify targeting criteria for online advertising campaigns based on natural query event data are described. A request to determine targeting criteria is received from an advertiser entity. Natural or algorithmic query event data related to the advertiser entity is retrieved from a data storage module. Attribute data associated with targeted customers is extracted based on the retrieved natural query event data. Finally, the attribute data is further processed to determine a set of criteria to target advertisements to the customers.
