Retargeting is at home in the field of digital marketing, eCommerce and digital commerce. The term describes an advertising method that targets people who have already visited a website or shown interest in certain products but have not yet made a purchase.
Imagine you are looking at shoes in an online shop but do not buy them. After your visit, you suddenly see adverts for exactly these shoes on other websites. This is retargeting. The shop "remembers" your visit with the help of small files, so-called cookies, and shows you the appropriate adverts again. The aim is to remind you of the product and persuade you to buy it after all.
Retargeting helps companies to utilise their marketing budgets in a more targeted manner and avoid wastage. Customers are shown adverts that really match their interests instead of being advertised to in general. This benefits shop operators and customers alike: The former increase their sales opportunities, while the latter receive relevant and often helpful offers.
