We recruit participants remotely from all around the world, and cannot guarantee that everyone will take your survey seriously, nor that they’ll give you answers you expect. Most participants will be great. A few might not be.

We can guarantee, however, that bad quality participants will be replaced at no charge. If you suspect this in your results, just contact support and we’ll fix it for you.

Rules for recruiting participants

Study must be live

Your study must be live before you can recruit participants so that they can receive a live study link. You'll see the option to order participants on your Studies dashboard::

:

Participants will be anonymous

Participants recruited via our service will not be asked for an email address or other identifier. Any other participants you invite will still be required to enter an email address or other identifier if set.

We ask that you don't ask for identifying information in pre- and post-study questions (names, emails, location, and so on). These questions will stop your order from being processed.

We make sure that your study meets these requirements before we send it to our participants.

Studies must be customized to match the language for your participants

 If you’re recruiting participants from other countries through our recruitment service, the language of your study needs to match the language of the country your participants are from. You can change the language of your study on the  Settings tab when designing your study. Any headings and buttons in your study will be automatically translated to the language you selected. 

You will still need to write your own pre- and post-study questions, tasks and instructions, as the default text is in English.

Use 'Preview' to see exactly which parts of your study are in the language you select.

Participants will not need a password

If set, participants you order through our recruitment service will not be required to enter a password. Any other participants you recruit yourself will still be required to enter the password you choose.

Participants will not be redirected

If you set a redirect URL on your survey, recruited participants will not be redirected on completion. They will see the ‘Thank You’ page instead. Any other participants you invite will be redirected.

OptimalSort card limits

Due to participation time limits from our recruiting partner, closed card sorts may have up to 90 cards and open card sorts may have up to 60 cards.

Getting more participants than you paid for?

At times, we provide extra participants to cover for any potential responses that for any reason don't meet our standards. You won't be charged for these participants.

For example, you might pay for 50 participants, and see that 67 participants have completed your task. In this case, you will only pay for the initial 50 participants you ordered.
