How can I ensure high quality survey responses?


All responses on Conjoint.ly are checked for signs of fraudulent or inattentive behaviour. Respondents are automatically marked as low quality if the following signs are present:

  • Short length of time spent on the full survey (e.g. 20 seconds);

  • Short length of time spent on each conjoint choice set (e.g. 1 second);

  • If a mouse is present on the device, but we do not detect movement of the mouse;

  • If scrolling is required to read the full question, but no scrolling occurs;

  • If certain unlikely answers are provided in open-ended questions.

Please note: If you are using our panel respondents, you do not pay for low-quality answers.

During your experiment’s setup, there are several options available to help filter out low-quality respondents;

  • Open your experiment under the “My experiments” option from the left-side menu.

  • Click the “Advanced Settings” tab and collapse the “Response quality management” and “Response quality warnings” modules for more options.

You can also specify a separate redirect for low-quality respondents;

  • Collapse the “Redirects upon survey completion” module under the “Advanced settings” tab.

  • Insert the re-direct URL in the “URL for low quality responses” form.

  • Click the “Save changes” button at the bottom-left of your screen.
