The embodiment of the invention provides an advertisement data aggregation query method and device. According to the embodiment of the invention, time information of advertisement data which terminalequipment needs to query is divided according to different time granularities to obtain time periods of the different time granularities; aggregation results of advertisement data in the time periodsof all the time granularities are respectively queried according to the time periods of the different time granularities; and then the aggregation results of the advertisement data in the time periodsof all the time granularities are aggregated into an aggregation result of the advertisement data in a time length on which the terminal equipment needs to carry out a query. Therefore, compared withcarrying out aggregation by the prior art on the basis of daily records of display, clicking and advertiser consumption, the method improves aggregation efficiency, and also improves query efficiencyof the aggregation result at the same time.
