First, all Target customers are assigned a Guest ID.
Associated with this ID is information on “your age, whether you are married and have kids, which part of town you live in,
how long it takes you to drive to the store, your estimated salary, whether you’ve moved recently,
what credit cards you carry in your wallet and what Web sites you visit.”
Pole found that by analyzing this data combined with purchasing history on 25 products – things like unscented lotion and certain types of vitamins — he could determine the likelihood that a woman was pregnant.
He quantified this information by assigning women a “pregnancy prediction” score; his data analysis was so good that he could estimate, within a fairly small window of time, a woman’s due date.
This further allowed Target to send the women coupons targeted at different stages of pregnancy.
Thanks for the info.
