The most basic and easy to understand type of retargeting is site retargeting. This very simple version of retargeting simply consists of placing a retargeting pixel on your site and creating a retargeting audience out of anyone who visits it. Now that you’ve determined these people have an interest in, and familiarity with, your brand, you can then retarget them in the future as a ‘warm’ audience and expect significantly better ad results than you’d experience with cold traffic.
