Facebook has teamed up with datalogix, a data company that is able to determine how effective the ads are by tracking what audience the actually purchases. Compiling this data will help companies see if their ads are working based on their in store sales.
Datalogix gets its information from retailers like grocery stores and drug stores who keep careful records of what its customers who use its loyalty discount programs are buying. Datalogix matches the email addresses and other identifying information in those databases to Facebook accounts.
To avoid user backlash, facebook has established a way to protect your privacy. Your profile will be anonymous, and in place of the real name of your profile there will be a hash. Users may also opt-out of the tracking system by accessing the datalogix website. Do you facebook will eventual suggest products and brands for you to like based on the data from your purchases?
