Product differentiation[1] is a marketing strategy[3] that businesses use to distinguish their products from similar offerings in the market. This approach involves creating a unique selling proposition or highlighting specific traits that make the product superior or different from its competitors. There are three main types of product differentiation: vertical, horizontal, and other types like spatial differentiation. Vertical differentiation refers to differences in quality and price, objectively measured by consumers. Horizontal differentiation, on the other hand, is subjective and related to personal preferences, such as color or flavor. Spatial differentiation considers geographical location as a differentiator. This strategy can lead to a competitive advantage[2], higher profits, increased consumer[5] value, and market segmentation[4]. However, it can also impact pricing and demand[6], especially in the presence of substitute goods.
At economics and marketing, product differentiation (or simply differentiation) is the process of distinguishing a product or service from others to make it more attractive to a particular target market. This involves differentiating it from competitors' products as well as from a firm's other products. The concept was proposed by Edward Chamberlin in his 1933 book, The Theory of Monopolistic Competition.
