Retargeting is advertising, or showing display ads, to people who have already indicated an interest in your brand by visiting your online store, but abandoned their shopping activity without buying. It works by keeping track of people who visit your site, then displaying your retargeting ads to them as they visit other sites online. Retargeting helps you reach your most valuable lost prospects—people who show enough interest in your products to have browsed your site. Retargeting brings these “window shoppers” back when they're ready to buy by keeping your brand foremost in your customer's mind. When visitors leave your site and browse the Internet, your ads will display on other sites they visit. A comScore study found retargeting resulted in a 1,046% lift in visitor traffic to a site when compared to advertising without retargeting.
