Sampling/Participant sample selection

We provide consumer sampling from our Consumer-Opinon panel, primarily samples for online surveys, compiled in accordance with your specifications.

We currently offer sampling for consumers resident in most european countrys. Panels in other countries outside Europe are in planning.

Initially you send us your enquiry for the required target group. We will process your enquiry, check in our database whether we can meet your requirements and send you a quote. You can get a rough idea of our attractive pricing structure on the Prices page.

In the case of online surveys, you, as the client, can program the questionnaire yourself using a system of your choice and host the study. You provide us with a test link to the study. We will check the technical aspects, methodology and length of your questionnaire and program survey access for our participants (transfer, see below).

We then send our test subjects an invitation by e-mail. The invitation tells our participants the length of the questionnaire and the amount of the incentive. We usually carry out an initial screening process to filter out suitable participants. A sample meeting your specifications is then given access to your questionnaire.

At the end of the survey, the test subjects come to an end page, where we realise the incentive. Once the required number of cases has been collected, let us know and close down the survey. We then calculate the central participation parameters (such as precise field time, number of times the questionnaire was called, aborted interviews, users rejected due to full quotas, completed interviews).

Technical procedure for supplying respondents
(in the case of sample provision)

The description below shows you in detail, how we usually deliver pure-sampling to the online-survey hosted by you:

Step 1: Links to the survey

The client provides a link to the survey, e.g.
http://www.customer.com/survey.htm

Step 2: Passing parameters to the external survey

We add two parameters to the client’s link(s):
id (participant’s panel ID, 8 characters)
qpw (individual study password, 8 characters)

The link(s) to the external survey will then have, as an example, the following form:
http://www.customer.com/survey.htm?id=[xxxxxxxx]&qpw=[yyyyyyyy]

Step 3: Performing the survey

The survey is carried out by the client. The URL parameters are normally passed automatically without requiring further action.

Step 4:
Return and notification of interview status...

After the survey, the client directs participants to our URL(s) and notifies us of the interview status, so that we can realise the participants’ incentives.

E.g.::
http://url/[Complete]?id=[xxxxxxxx]&qpw=[yyyyyyyy]
http://url/[Screenout]?id=[xxxxxxxx]&qpw=[yyyyyyyy]
http://url/[Quotenabweisung]?id=[xxxxxxxx]&qpw=[yyyyyyyy]

or:
http://url?id=[xxxxxxxx]&qpw=[yyyyyyyy]&qi=[Interview-Status]

... or termination and generation of a list

If it is not possible to automatically return participants to the URLs given, the client must send us a list of participant IDs and interview status. In addition, the client must provide end pages for completes, screen outs and quota fulls. We provide text modules for this which the client should integrate into the relevant end page.
