Basic Training of our researchers and shoppers includes:
  • Overview of marketing research

Additionally, all interviewers are briefed on a project-by-project basis. Their work is monitored and validated to ensure compliance with NSS, your company, and other industry quality standards.

Auditing the Researcher's Performance
National Shopping Service has several checks and balances in place to make sure that researchers provide you with fair, accurate, and dependable feedback. At NSS we audit our researchers' scoring habits, rotation and frequency habits, and even utilize a rating system to ensure that scoring is not biased.

Advanced Scheduling and Rotation Techniques

Mystery Shop Scheduling

  • Schedulers are trained in your company's exact operating standards.
  • Schedulers use a sophisticated, customized computer system that prompts them through each instruction they need to share with the mystery shopper before the visit is performed
  • Scheduling program strictly enforces all of the rotation and filtering rules in place for your account such as shopper age requirements, income, days apart, etc.

Selecting Shoppers/Researchers that are right for you
One of the features that sets National Shopping Service apart from other mystery guest companies is its mystery shopper "Profiling" methodology. We maintain an in-depth database on all of our field representatives and mystery shoppers. Each field researcher is profiled to determine his or her own natural purchasing, dining, and consuming habits. This allows us to ensure that we are matching the profiles of our shoppers up with the profiles of your normal, targeted customer. We will work with you to determine a shopper profile that meets your unique target market.

Proofing Pipeline

From designing a meaningful form to resolving client requested adjustments, our proofing pipeline is built from the ground up to transform raw bits of experience into sound and actionable business feedback.

Our standardized applications and refined methodologies are specifically designed with these checks and balances to verify constant adherence to our high statistical and editing standards.
