The document discusses different types of market segmentation. Market segmentation involves dividing buyers into internally similar groups based on characteristics like demographics, behaviors, or geographic location. Segmentation allows companies to target specific buyer groups and better appeal to their needs. Common bases for segmentation include geographic location, demographics (age, gender, income), psychographics (lifestyles and attitudes), and benefits sought. Demographic segmentation using variables like age, gender, household size is very common. Segmentation provides insights into how to reach different buyer groups.
