Marketing channels refer to the intermediaries used by companies to distribute products to consumers. Channels play an important role in delivering value by physically distributing products and providing supporting services. There are different types of marketing channels that vary based on their functions and characteristics. When designing a channel system, companies must consider objectives, customer and product characteristics, and available resources to determine the appropriate channel intensity and structure. Both choosing the wrong channel intensity and failing to properly manage selected channels can negatively impact sales and productivity.
