Become a Mystery Shopper

We employ mystery shoppers (also known as secret shoppers or mystery shopping assessors) who experience a service or a brand through visits, telephone calls or online assessments. We then ask them to complete an online survey that provides a detailed picture of their own customer experience. In return for their services, they receive a fee and/or complimentary products or services.From individual retail outlets and restaurants, to global financial institutions and technology companies; GfK’s mystery shoppers help our clients deliver excellent customer service and their brand's true value. We do much of our work undercover, but we also offer professional auditors who work openly.
