Retargeting (Remarketing) is a form of online advertising which consists of displaying ads to website visitors based on their previous interactions and behaviors. In other words, people that have visited and interacted with your website but left, may see ads incentivizing them to come back.
This process is used to build up your brand awareness with potential customers who are interest in your product or service.
Retargeting ads may contain specials offer incentives, customer success messaging, product review or different forms of highly targeted messaging based on the retarget group.
