Remarketing, also known as retargeting, it is the practice of engaging with consumers who have already interacted with your brand. The purpose is to drive desired actions, but usually with a higher engagement and conversion rate because your consumers have shown prior interest in your brand, products or services.
This is a paid marketing strategy that often involves content such as display ads. It can help remind and prompt consumers to take action, and is particularly effective if you’ve already provided something of value to them (such as an educational blog post).
