The document compares online and offline marketing. It begins by defining offline marketing based on definitions from authors like Kotler and the Chartered Institute of Marketing. Offline marketing is described as a social and managerial process of identifying, anticipating, and satisfying customer needs profitably through products, pricing, promotion, place, and personal selling. The document then discusses how online marketing differs from offline marketing in its functions and instruments, such as individualization, auctions, and social media marketing. It argues that while online and offline marketing share concepts, the specifics of how they are implemented differ. The key challenge for companies is to thoughtfully coordinate their online and offline marketing strategies.
