The approach that would provide a predictive audience for your e-commerce site is: "You create an audience of users who are likely to purchase in the next seven days." This method uses predictive analytics to segment users based on their future behavior, allowing you to proactively target and engage potential customers who show signals of purchase intent. It leverages machine learning models analyzing patterns such as browsing history, items added to cart, and time spent on the website to forecast purchase likelihood. This predictive segmentation helps drive conversions and revenue growth by focusing marketing efforts on users with a high propensity to buy soon.
