In accordance with the teachings described herein, systems and methods are provided for measuring the effectiveness of an advertising display. A radio frequency identification (RFID) tag may be associated with an advertising display in a retail environment. One or more receivers may be used to receive an RFID signal from the RFID tag. One or more processors may be used to receive the RFID signal from the receivers to determine a time period during which the advertising display is located within the retail environment. The one or more processors may also receive sales data from the retail environment relating to an amount of sales of one or more products associated with the advertising display over the time period that the advertising display is located within the retail environment. The one or more processors may compare the sales data with one or more sets of control data to measure the effectiveness of the advertising display.
