A system, method, and computer-readable medium are disclosed for managing the display of product module descriptors within a user interface. Product module data, along with historical visit and product module purchase data, is processed to generate a Config Score numeric value, which in turn is processed to generate a ConfigRank numeric value for each of a plurality of product modules. In turn, the ConfigRank numeric values are then used to determine the placement of each product module's associated product module descriptor within a user interface window.
