We give you three options when indicating how often you want visitors to see your survey:
Only once per visitor: The most polite and non-intrusive of the options. If we determine this particular visitor has already seen this specific survey, we do not show the survey again, even if they didn't respond.
Continue showing until the visitor provides a response: We'll continue showing the survey, regardless of how many times the visitor has seen the survey, until they provide a response. This includes partial responses.
Continue showing even if a visitor has responded: The most aggressive of the three options, and the best option to select if you're testing your survey!
