All of the methods of attracting the customer to the site in order to interpret the customer or the user according to their behavior and then make a new purchase can be called "remarketing".
When a customer who enters the e-commerce site and exhibits certain behaviors leaves the site without making a purchase, the customer can be encouraged to come back to the site and make that purchase in various ways, depending on the attitude they display on the site. In this way, the page views such as product and category of the site can be increased and the conversion rate can be increased as a result.
