The document discusses market segmentation, targeting, and positioning (STP). It defines segmentation as classifying customers into groups, targeting as selecting segments to enter, and positioning as arranging a product to occupy a clear place in customers' minds relative to competitors. The key steps are: 1) identifying segmentation bases; 2) developing segment profiles and selection criteria; 3) choosing target segments; 4) developing a position for each; and 5) creating a marketing mix for each. Effective segmentation requires segments be measurable, accessible, substantial, and differentially responsive to marketing activities. The document also discusses evaluating and choosing target segments and strategies for coverage, as well as developing competitive advantages and supporting a positioning strategy with a unique marketing mix.
