Retargeting, also known as remarketing, is the same thing as Display with the only difference being who is being targeted. These banners can appear on the right, top, bottom, or middle sections of a webpage. Display banners typically target users based on contextual targeting or interest categories. Retargeting on the other hand, only targets the users who have already visited your website identified by the cookies in their browsing history. These users are dumped into a retargeting list, which can allow you to “follow” them around the internet for a selected period of time (30 days, 60 days, etc.)
