Closed-Loop Marketing is a marketing strategy that involves retargeting past customers to make the most out of the marketing campaign. This form is also called “Retargeting” because it is based on retargeting customers that have either searched for your product or service or have already purchased your products or services. The goal of Closed-Loop Marketing is to focus on bringing back customers rather than attracting new ones. The potential for success with this strategy lies mainly because these are customers who have already expressed interest in your business and what it has to offer, so there is no need to worry about bringing them over from other competitors.
