Retargeting is a way of reaching and targeting users with personalized offers who have already visited our website and are therefore likely to be familiar with our services. Remarketing can help us improve the effectiveness of our campaigns and the conversion rate of our users. Remarketing campaigns not only allow us to retarget people who have already visited our website, but also, through the use of Google Analytics or marketing automation tools, to group users into groups based on their activity and behavior, and target these groups with different banners and messages.
