Abstract: Systems and methods for determining content effectiveness are disclosed. In some examples, a media device in a store of an entity displays content about a product. Shopping assistant devices owned by the entity are used by customers to assist their shopping in the store. Each of the shopping assistant devices has an asset identifier (ID). A first sensor is configured to detect a first set of asset IDs coupled to a first set of shopping assistant devices. At least one second sensor is configured to detect a second set of asset IDs coupled to a second set of shopping assistant devices. At least one processor is configured to: obtain purchase data associated with the second set of shopping assistant devices; and determine an effectiveness of the content based on information about: the first set of asset IDs, the second set of asset IDs, the product, and the purchase data.
