Survey Options: Survey Protection

Qualtrics offers numerous ways to protect your survey from unsolicited responses. You can limit who has access to your survey by allowing only those with an invitation to take your survey, or you can protect your survey with a password. You can limit the number of times an individual takes your survey by using the Qualtrics' ballot box stuffing prevention capabilities. You can also set up your survey with HTTP referer verification, so only respondents coming from a specific website will be able to take your survey.
