What is essential for tracking unique responses in Qualtrics?

Using personal links is essential for tracking unique responses in Qualtrics because these links are specifically generated for individual respondents. Each personal link is unique to a specific participant, allowing researchers to identify who completed the survey while maintaining the integrity of their responses. This unique identifier helps in analyzing the data based on individual input and facilitates follow-up if necessary.

In contrast, anonymous surveys do not allow for unique identification, making it impossible to track who submitted each response. Standard links, while they can collect responses, do not provide the unique tracking functionality needed if the same link is shared among multiple respondents. Public links are similar to standard links in that they do not allow for individual tracking, as they can be accessed by anyone, thus losing the ability to monitor who has or hasn’t completed the survey. Using personal links ensures that data collection is both accurate and linked to individual respondents.
