To reach a high quality of the sample we always pay attention to the quality standards of the access-pool.

The interviewees are recruited from wide spread different resources. Especially, we are concentrating on active recruiting and ask people around the world to join based on intrinsic interest.

Cleaning & maintenance of multiple registrations by verified postal address

All interviewees can be verified by their phone number and postal address. Only one registration is allowed per household.

Our panel management experts prevents interviewees to participate too often. By the concept of direct compensation, the experts are willing to participate in less than 4 surveys a year in contrast to incentive programs where threshold must be reached to get the incentive.
