Dynamic Product Ad is used to retarget audiences who previously visited your product pages or added items to their cart. The system delivers the dynamic ad based on individual customer's data, interest in products, and previous behavior on the website. Hence, every individual will receive a personalized ad experience, and view different products in the same campaign set. This type of ad is good to remind customers to purchase products they expressed interest in, convert store visitors into customers, cart abandoners, and for existing customers to repurchase.
