Are you familiar with the concept of retargeting? I’ll bet it’s happened to you. You’re online shopping for an item…let’s say a new pair of shoes. You examine the features, check the price, you may even click to add it to your shopping cart, but you never complete the purchase. The next time you’re online you’re served an ad for that exact pair of shoes. Weird? Nope, that’s a form of retargeting.
