The four types of consumer buying behavior are: Complex buying behavior: The customer is highly involved and does extensive research before purchasing a product. Dissonance-reducing buying behavior: The customer is uncertain about the product and seeks information to avoid buyer’s remorse. Habitual buying behavior: This customer purchasing behavior doesn’t factor in much thought or research. Variety-seeking buying behavior: Customer seeks out new experiences and trial of different products.  Understanding these behaviors can help businesses tailor their marketing strategies and meet the needs of different customer segments.
