What are the main forms of market segmentation and product classification?

"Success in marketing depends on understanding the target market. One technique used to identify a target market is market segmentation. The five basic forms of segmentation are demographic (population statistics), geographic (location), psychographic (personality or lifestyle), benefit (product features), and volume (amount purchased). Business markets may segment based on geography, volume, and benefits, just as consumer markets are. However, organizations might also segment based on use of the product, characteristics of purchasing function, and size of the client or industry, as well as other considerations related to characteristics of business customers. Volume segmentation is the differentiation of markets based on the amount of the product purchased. A product can be a good, service, or idea, along with its perceived attributes and benefits, that creates customer value. Tangible attributes include the good itself, packaging, and warranties. Intangible attributes can include the brand’s image or relational attributes such as the credibility of its service providers. Products are categorized as either consumer products or business-to-business products, which can be commercial, industrial, or services products. Consumer products are bought and used by the end user, sometimes called “the ultimate consumer.” They can be classified as unsought products, convenience products, shopping products, or specialty products, depending on how much effort consumers are willing to exert to get them. Unsought products either are not planned as a purchase by a potential buyer or are known but the buyer does not actively seek them, such as funeral services. Specialty products are items for which consumers search long and hard and for which they refuse to accept substitutes. Business-to-business products are those bought by organizations for use in making other products or in rendering services to other organizations and include capital products and expense items."
