An athletic apparel company notices customers frequently purchase running shoes but rarely buy matching athletic wear. They want to promote their new apparel line to existing shoe buyers. Which audience strategy best addresses this cross-sell opportunity?

Rule-based audiences in Amazon Marketing Cloud are used to define audiences from specific behavioral conditions. Prior running shoe purchase activity identifies existing customers with category interest. Excluding athletic wear purchasers keeps the audience focused on the cross-sell opportunity. This creates a precise audience for promoting the apparel line to customers who have not yet purchased the complementary product.
