Behavioral retargeting

Behavioral Retargeting is a way of showing you ads on different websites based on the things you looked at online. Say for example, you looked at a pair of shoes at an online store. Then, when you go to different websites you visit online, you might start seeing ads for that same pair of shoes. That's because those websites are using Behavioral Retargeting to show you an ad for what you recently looked at.
