Final answer:
Fostering positive word-of-mouth for a business involves excellent customer service and resolving any issues proactively. Guarantees, certifications, and assurances like cosigners can reduce the risk of imperfect information in transactions.
Step-by-step explanation:
To ensure positive word-of-mouth marketing in a business, focus on delivering exceptional customer service, quality products, and building a strong reputation. Regularly engage with customers and request feedback to improve services. If negative information is shared, address it promptly and professionally, seeking to resolve the customer's concerns and demonstrate a commitment to excellence.
As for reducing the risk of imperfect information when selling, use guarantees, warrantees, and service contracts to demonstrate the quality of your products. For those in professional services, having occupational licenses and certifications can reassure customers of competency. In financial dealings, cosigners and collateral serve as additional assurance against unforeseen events.
