Ad Retargeting is a smart online marketing technique where, after a user visits a website without committing to making a purchase, ads for that website appear on other websites that the user visits. This is known as a “retarget” or “retargeting” strategy. Retargeting is a great way to remind users of products they were interested in but didn’t end up buying. You know how you might look at a pair of great t-shirts online before you decide to buy them? Well, with ad retargeting, the t-shirts follow you online. They show up on several websites and ask, “Do you remember me? I think you liked me.” The internet remembers everything, and it seems like it’s trying to influence you about those t-shirts.
