Psychographic segmentation divides audiences based on lifestyle traits, social class, and behaviors. It uses demographic data to understand audiences' behaviors, habits, and psychologies. Marketers obtain psychographic data from various sources like surveys, social media, and focus groups. Psychographic segmentation involves dividing audiences into groups according to social class, lifestyle characteristics defined by models like the 4Cs, and behaviors related to product usage, benefits, and loyalty. It also segments based on buyer readiness stages that range from awareness to purchase.
