According to the data released at the Facebook Ads Summit in July 2025, dynamic ads targeting users who "haven't placed an order in 7 days" can increase the repurchase rate by 35%. Some merchants, through a customized "abandoned - cart recall plan", use the user behavior tracking function to capture the browsing records of users who added items to the cart but didn't place an order, and then launch relevant dynamic ads with a "specific $5 coupon". As a result, the abandoned - cart rate dropped to 40% within two weeks, and the repurchase orders increased by 25%.
