Intensity refers to the number of intermediaries at each level of the marketing channel. Intensive: sometimes called saturation means that as many outlets as possible are used at each level of the channel.
Selective: means that not all possible intermediaries are used, but rather those included in the channel have been carefully chosen.
Exclusive: a way of referring to a very highly selective pattern of distribution.
The intensity of distribution dimension is a very important aspect of channel structure because it is often a key factor in the firm’s basic marketing strategy and will reflect the firm’s overall corporate objectives and strategies.
