Abstract: In some embodiments, a method defines a control group of consumers from a population of consumers that meet a first criterion associated with a promoted entity. The method further includes calculating an aggregate first per-consumer-purchase amount for the promoted entity based on one or more consumer characteristics of the control group. The method further includes defining a test group of consumers from a population of consumers that meet a second criterion associated with the promoted entity, and calculating an aggregate second per-consumer-purchase amount for the promoted entity based on the one or more consumer characteristics of the test group. The method further includes sending a signal indicative of a net purchase value based on a difference between the aggregate first per-consumer purchase amount and the aggregate second per-consumer-purchase amount.
