There are two different promotion strategies as push promotion and pull promotion. In the push strategy, promotional efforts are directed to sales force and intermediaries like the retailers. For example, a company may use trade promotion if it wants retailers to give a special support to the sales of a product. In return, the retailer promotes the product to its customers. Another example to push a product through channels may be a sales contest for the salesforce. The sellers may be offered a big prize if they sell a certain amount of product to the retailers.
