An ecommerce event is a type of event that enables you to understand the user activity on an ecommerce website or mobile app. To find a list of ecommerce events, see Recommended events.
Each ecommerce event enables you to measure a specific aspect of your store. For example, setting up the purchase event lets you understand purchase behavior, while setting up the add_to_cart event lets you understand add-to-cart behavior. To learn how to set up ecommerce events, see Ecommerce in Google Analytics.
