Mystery shopping is a unique way for companies to evaluate their customer service and product quality. There are several synonyms for a mystery shopper, including secret shopper, anonymous evaluator, undercover customer, covert consumer, and research investigator. These individuals are hired by companies to act as typical customers and report their experiences to the company for evaluation. The feedback received from a mystery shopper can help companies identify areas of improvement and refine their offerings. With the rise of online shopping, mystery shoppers can also assess the quality of delivered goods and the customer service provided by call centers and online chat support.
