Unlike ads that appear as a direct result of a search, display advertising appears next to content on news sites, blogs and other niche sites across the Internet. Display (or banner) ads are graphical advertising that can include logos, images, and rich media.
Retargeting brings back visitors who have left your website without taking action. As they visit sites within the display ad network, retargeting technology serves up customized display ads about your company or the product they just searched for, reminding them of their purchase intent.
