Customer loyalty refers to the strong and unwavering commitment of a customer to a particular brand, product, or service. It is the result of a positive and consistent experience that a customer has had with a company, leading to a deep sense of trust and satisfaction. This loyalty is not just based on repeat purchases, but also on the emotional connection and loyalty that a customer feels towards a brand. It is a crucial aspect of building a successful and sustainable business, as loyal customers not only continue to support a company, but also become advocates, spreading positive word-of-mouth and driving new business.
