This document discusses market segmentation, targeting, and positioning. It begins by defining market segmentation as dividing a broad market into subsets with common needs and interests. The four factors that affect segmentation are clear identification, measurability, accessibility, and appropriateness for a company's resources. Segmentation strategies include behavioral, demographic, psychographic, and geographic differences. Market segmentation allows companies to devise tailored strategies for each subset. The document then discusses the steps in segmentation, targeting, and positioning, including identifying segments and competitors, determining perceptions, selecting target markets, and monitoring positions over time.
