Referrals are recommendations made by one person to another, suggesting a service or product. They often occur in business settings, where satisfied customers share their positive experiences with friends or colleagues. This word-of-mouth marketing can help businesses gain new clients and build trust. In many industries, such as healthcare or real estate, referrals are crucial for growth. For example, a doctor may refer a patient to a specialist for further treatment. Similarly, a real estate agent might recommend a mortgage broker to clients seeking financing. Referrals can enhance credibility and foster long-term relationships.
