My niece is about to get her drivers permit and she has big (read: unrealistic) dreams of her first car. Last weekend, she asked my sister if she could borrow her laptop to research potential vehicle options and spent over an hour comparing body types and options and researching prices. Apparently, she spent quite some time researching Audi and BMW SUV’s as well as a few more reasonable Honda options. Fast-forward to that evening when my sister went online to check out her Facebook feed. Lo and behold, there was ad after ad from local car dealerships and pictures of the “way out of her price range” SUV’s my niece had spent the day researching. How in the heck did that happen? She hadn’t researched these cars, why are ads for them showing up in her feed? Simple answer: retargeting from pixels to her computer’s IP address that had captured search history that day.
