A channel level (or marketing channel level) is any layer of marketing intermediaries (wholesalers, retailers, agents) that perform some work to bring the product and its ownership closer to the end user. The number of these levels determines the length of the marketing channel.
A zero-level channel (direct marketing) has no intermediaries. A single-level channel involves a single intermediary (e.g., a retailer). The strategic choice of the number and type of levels depends on the characteristics of the product, the target market, and the desired level of distribution control. Each additional level increases cost and complexity, but can improve the effectiveness of reaching the market.
