OFFLINE-SALES ATTRIBUTION SYSTEMS AND METHODS

摘要

An offline transaction may be attributed to an online activity by receiving a request from a consumer device for a resource that comprises a vendor page. An online-referral source (by which the consumer device identified the vendor page) is determined, and a unique identifier, the online-referral source, and the vendor page are stored in a persistent record. A device-identifier association is created to associate the unique identifier with the consumer device. Subsequently, offline-transaction data is obtained, associating an online-communication address with an offline transaction involving the vendor and an individual or. When a second resource request is received from the consumer device, it is determined to be associated with the unique identifier, and further, that it is associated with the online-communication address and the offline transaction. The vendor is notified that the offline transaction is associated with the online-referral source.
