Process of dividing the market according to similarities that exist among the various subgroups within the market. The similarities may be common characteristics or common needs and desires. Market segmentation comes about as a result of the observation that all potential users of a product are not alike, and that the same general appeal will not interest all prospects. Therefore, it becomes essential to develop different marketing tactics based on the differences among potential users in order to effectively cover the entire market for a particular product. There are four basic market segmentation strategies: behavior segmentation, demographic segmentation, geographic segmentation, and physiographic segmentation.
