Invite Participants By Website Interceptions
Interception consists of automatically inviting certain visitors of your web site to complete your online survey. Only visitors that meet certain interception criteria will be invited to complete your survey. Visitors who decline the invitation will not be re-invited, unless they erase their browser cookies.
To automatically invite your web site visitors to participate in your online survey, you will need to create an Intercept and integrate it into your web site. See the help on Intercepts.
