Promotion comprises four subcategories: 1)Advertising 2) Personal selling 3)Sales promotion 4)Publicity and public relations

The specification of these four variables creates a promotional mix or promotional plan. A promotional mix specifies how much attention to pay to each of the four subcategories, and how much money to budget for each. A promotional plan can have a wide range of objectives, including: sales increases, new product acceptance, creation of brand equity, positioning, competitive retaliations, or creation of a corporate image.
