Retargeting, also known as remarketing, is digital advertising that features specific products or services and targets an individual who has viewed them online. Customers and leads already in an advertiser's database may also be subjects for retargeting. Retargeting is the technology behind ads that follow people from one site to another.
List-based retargeting is aimed at existing contacts in a business’ database. The process involves uploading a list of their email addresses to a remarketing platform, typically for a social media campaign on Facebook or Twitter. The platform identifies users on the list and serves the ads only to them.
The principle behind remarketing is the Rule of Seven, an advertising concept holding that a consumer typically has to encounter a given marketing message seven times before making a purchase.
