A
market segment is a group of people or organizations sharing one or more characteristics that cause them to have similar product and/or service needs. A true market segment meets all of the following criteria it is distinct from other segments (different segments have different needs), it is homogeneous within the segment (exhibits common needs); it responds similarly to a market stimulus, and it can be reached by a market intervention. The term is also used when consumers with identical product and/or service needs are divided up into groups so they can be charged different amounts. These can broadly be viewed as 'positive' and 'negative' applications of the same idea, splitting up the market into smaller groups.
Market segmenting is the process that a company divides the market into distinct groups who have distinct needs, wants, behavior or who might want different products & services. Broadly, markets can be divided according to a number of general criteria, such as by industry or public versus private although industrial market segmentation is quite different from consumer market segmentation, both have similar objectives. All of these methods of segmentation are merely proxies for true segments, which don't always fit into convenient demographic boundaries.
Consumer-based market segmentation can be performed on a product specific basis, to provide a close match between specific products and individuals. However, a number of generic market segment systems also exist, e.g. the Nielsen Claritas PRIZM system provides a broad segmentation of the population of the United States based on the statistical analysis of household and geodemographic data.
The process of segmentation is distinct from targeting (choosing which segments to address) and positioning (designing an appropriate marketing mix for each segment). The overall intent is to identify groups of similar customers and potential customers; to prioritize the groups to address; to understand their behavior; and to respond with appropriate marketing strategies that satisfy the different preferences of each chosen segment. Revenues are thus improved.
