Multi-use links

Multi-Use links can be used as many times, and by as many participants, as you need.

  • This is useful when participants don't have to be identified.
  • Add the link to:
    • The body of an email inviting participants to the study
    • Banners on your site
    • As a link on your website
    • Any other invitation method you choose
  • If you use Multi-Use Links as a clickable link on your website:
    • Add target="_blank" in the anchor element (<a>) in the HTML code.
    • This opens the study in a new tab so participants don't lose their current page.
  • You can configure whether the study can be completed on the same computer only once.
    • This allows participants to leave the study before finishing and come back to continue from where they left off as long as their browser session is active.
    • When they complete the study, they can't take the study again.

Panel links

Use Panel Links when recruiting participants through a Panel Provider.

  • The Panel gives a unique parameter for each participant.
  • This allows you to:
    • Identify participants individually
    • Merge the data and/or variables gathered in the vendor panel's screener with the data gathered in your study.
  • For more information, see Recruiting participants through an external panel vendor.


Get Panel Links

  1. Go to the Recruitment section of your study.
  2. Select the Segment.
  3. In Recruiting Methods, click Invitation Links.
  4. Choose Show panel and Single-use links.
  5. Click Copy Panel Link.


Add a unique parameter to Panel Links

  • There are two options when it comes to adding this unique parameter to the Panel Link.
  • For both options, replace the PARTICIPANTID part with a unique ID for each participant.
  • If the PARTICIPANTID parameter is not changed for a unique parameter for each participant:
    • The Participant ID will be the actual text: PARTICIPANTID
    • Only the first participant would be able to complete the study
  • Regarding the PARTICIPANTID parameter, keep in mind that:
    • It is defined at the study level and its values can't be repeated in the same study, not even in different segments.
    • The maximum length is 101 characters.
    • It can't contain any of these characters: . _ ~ : / ? # [ ] @ ! $ & ' ( ) * + , ; = |
  • These variable names can't be used as they already exist in our system: ioriuuclnuzsidtic
  • When working with Panel Invitation Links:
    • Configure Redirect Links to direct participants to the Panel Vendor's Final Pages.
    • Optionally, include the participant ID and/or segment to which the participant belongs.


Option A

Replace the final part of the Panel Link (PARTICIPANTID) with a unique parameter for each participant. For example:

  • Segment 1:
  • Segment 2:


Option B

  1. In the Panel Link, replace the parameter /p/ with /q/.
  3. Replace the PARTICIPANTID parameter with the unique parameter for each participant.

Single-use or Unique links

  • Use Single-Use Links when recruiting participants through personalized invitations.
  • Match the unique invitation links with each participant by:
  • Single use-links allow the participants to:
    • Complete a study one time
    • Leave a study at any point, come back, and start where they left off

  2. Select the Segment.
