Market Segmentation

In marketing jargon, customer segments must be measurable by clear characteristics; they must be large enough to constitute a market; reaching them should be predictably easy (they all watch American Idol, for example, or subscribe to one of four magazines); they must be predictably responsive to marketing; the segment must be stable over time and not a one-time aggregation.

Determining how to segment a market is one of the most important questions a marketer must face. Creative and effective market segmentation can lead to the development of popular new products; unsuccessful segmentation can consume a lot of dollars and yield nothing. There are three main types of segmentation bases for businesses to consider—descriptive, behavioral, and benefit bases—each of which breaks down into numerous potential customer traits.

Descriptive bases for market segmentation include a variety of factors that describe the demographic and geographic situations of the customers in a market. They are the most commonly used segmentation bases because they are easy to measure, and because they often serve as strong indicators of consumer needs and preferences. Some of the demographic variables that are used as descriptive bases in market segmentation might include age, gender, religion, income, and family size, while some of the geographic variables might include region of the country, climate, and population of the surrounding area.

Behavioral bases for market segmentation are generally more difficult to measure than descriptive bases, but they are often considered to be more powerful determinants of consumer purchases. They include those underlying factors that help motivate consumers to make certain buying decisions, such as personality, lifestyle, and social class. Behavioral bases also include factors that are directly related to consumer purchases of certain goods, such as their degree of brand loyalty, the rate at which they use the product and need to replace it, and their readiness to buy at a particular time.

Businesses that segment a market based on benefits hope to identify the primary benefit that consumers seek in buying a certain product, then supply a product that provides that benefit. This segmentation approach is based upon the idea that market segments exist primarily because consumers seek different benefits from products, rather than because of various other differences between consumers. One potential pitfall to this approach is that consumers do not always know or cannot always identify a single benefit that influences them to make a purchase decision. Many marketers use a combination of bases that seem most appropriate when segmenting a market. Using a single variable is undoubtedly easier, but it often turns out to be less precise.

THE SEGMENTATION PROCESS

The process itself begins with narrowing the universe to be studied into a specific market now served by the company and obtaining basic information on competing products or services now on offer. Once this step has been completed, variables to be used are identified, reviewed, and tested. At the most basic level such variables, for example, might involve income and demographic characteristics of the consumers.

With these preparations completed, actual market research is organized to collect and to analyze data on the selected broad body of consumers. Analysis of the data will begin to cluster the consumers into distinct groupings based on the variables. Additional analysis, possibly involving more research, will next be conducted to develop detailed profiles of each segment already identified.

If the right variables were chosen at the outset and the market research was competently done, the resulting groupings will have characteristics distinct enough, and documented well enough, to permit the company to select one or more segments which will be easiest or more profitable to serve. The company's own strategy will play a role. Its aim, for example, may be use its capacity more fully and the company will therefore select a segment which will purchase the largest volume; alternative the company's aim may be low production levels with high profits, leading to a focus on another segment.

The last stage of the segmentation process will be the development of product and marketing plans based on the segment(s) most closely matching the company's "ideal" situation.

In general, customers are willing to pay a premium for a product that meets their needs more specifically than does a competing product. Thus marketers who successfully segment the overall market and adapt their products to the needs of one or more smaller segments stand to gain in terms of increased profit margins and reduced competitive pressures. Small businesses, in particular, may find market segmentation to be a key in enabling them to compete with larger firms. Many management consulting firms offer assistance with market segmentation to small businesses. But the potential gains offered by market segmentation must be measured against the costs, which—in addition to the market research required to segment a market—may include increased production and marketing expenses.
