Define customer loyalty.

Customer loyalty refers to a customer's commitment to repurchase or continue using a specific brand over time. This commitment is often built through positive experiences with the product or service, trust in the brand, and satisfaction with the overall customer experience. Loyal customers are likely to return, make repeat purchases, and recommend the brand to others, which can significantly benefit a business.

In contrast, the other options do not accurately capture the essence of customer loyalty. For instance, the willingness to explore different brands suggests a lack of commitment and indicates that the customer might prioritize variety over loyalty. A trend of customers switching brands frequently highlights a market characterized by instability rather than loyalty. Lastly, collecting customer feedback is important for understanding customer needs and improving services but does not define loyalty itself; rather, it is a tool that can help build loyalty. Customer loyalty is fundamentally about a lasting relationship based on trust and satisfaction, making the commitment to repurchase the key factor in its definition.
