When running a survey that is similar or identical to one you’ve run recently, you might want to ensure you are sending it to a completely new sample each time. Using the exclude respondents feature allows you to prevent people who have already taken a previous survey from being included again.
The same feature is also useful when running multiple surveys with different creative assets. By ensuring respondents only see one version, you can reduce bias and improve the reliability of your A/B test results.
If your survey is a tracker, a three-month exclusion is automatically applied. This prevents the same respondents from completing the survey too frequently and helps keep your results representative of a wider audience over time.
As a general rule, excluding respondents from surveys that ran six or more months ago is not recommended, as it can considerably reduce your available sample.
How to set up exclusions
When you've drafted your survey and you are moving on the Audience page, you'll see the option to Exclude respondents.
When you click on Exclude respondents, you will have the option to select one or more surveys. Selecting a survey (or multiple surveys) will exclude those respondents from answering the survey you’re drafting. Select the previous (open, scheduled or closed) surveys you wish to exclude. You cannot select to exclude draft surveys, as they don’t have respondents.
You can use the search bar to find surveys by external or internal title.
Check the Selected tab to see the surveys you’ve chosen to exclude. Click Save Exclusions and continue to complete your draft survey.
