Abstract: A system and method for tracking car sales by a car seller. After selling a car to a car purchaser personal identifying information is obtained from the car purchaser. The personal identifying information may be exported to an onboarding module which attempts to match the personal identifying information to identifying information assigned to an active user of third party website. Electronic identifying information of the active user received from the third party website may be matched to the car purchaser. The electronic identifying information may then be matched to an electronic identifier stored by the car seller of a viewer of car advertisements to determine an advertisement viewing history of the car purchaser.
