This document discusses customer loyalty from three perspectives: attitudinal and behavioral components of loyalty, factors that affect customer loyalty, and perspectives of customer loyalty. It defines customer loyalty as a commitment to a brand based on favorable attitudes and repeat purchases. Key factors that influence loyalty include customer satisfaction, emotional bonding, trust, habit, and history with a company. Loyalty can be demonstrated through attitudes, behaviors, or a desire to maintain a relationship. Competitive offerings, variety-seeking, low involvement, and insufficient marketing can lessen customer loyalty over time.
