Targeting is the practice of specifying a valuable audience that you want to serve ads to and applying a commercially attractive approach to that audience. In other words, targeting involves knowing who you are focused on and how best to appeal to them in order to provide a personalized experience.
Retargeting is the practice of serving ads to a user based on data very recently collected about the user's tastes, habits, and characteristics. It extends targeting.
At iPromote, retargeting is mainly realized through "pixels" and cookies, often working together. In a nutshell, a user interacts with an iPromote ad or advertiser website, and we record that interaction for future retargeting.
Retargeting provides an even more highly valuable impression than targeting because you operate on even more specific and recent data. It ensures that your spend goes where it is most effective.
