Is it best practice to create a new survey or just reuse my favorite surveys over and over?

It depends on what you want to achieve. If you have one survey that you want to refine over time, we suggest reusing it and making edits to it. However, if you want to compare different kinds of survey results, or you want to survey for different types of information, we recommend creating a new survey to make it easier for you to get the right kind of statistics.
