Question: Describe the types of marketing channels and the roles they play in marketing strategy. Marketing (distribution) channels are the systems of marketing institutions that enhance the physical flow of goods and services, along with ownership title, from producer to consumer or business user. In other words, they help bridge the gap between producer or manufacturer and business customer or consumer. Types of channels include direct selling, selling through intermediaries, dual distribution, and reverse channels. Channels perform four functions: facilitating the exchange process, sorting, standardizing exchange processes, and facilitating searches by buyers and sellers.
