Online-to-Offline Commerce is a business strategy that draws potential customers from online channels to make purchases in physical stores. Online-to-offline commerce, or O2O, identifies customers in the online space, such as through emails and internet advertising, and then uses a variety of tools and approaches to entice the customer to leave the online space. This type of strategy incorporates techniques used in online marketing with those used in brick-and-mortar marketing. O2O is related to (but not the same as) the concepts of “clicks-to-bricks” or “click and mortar.”
