If you are sending and creating numerous surveys at your company, you may wish to use tags to find a specific survey in the future more easily. Admins can generate survey tags by navigating to 'Settings' > 'Module & feature settings' > 'Surveys' > 'Survey Tags'.
Survey owners / admins can then add tags during survey setup in the 'Basics’ section under where you define the title, description, and owners of the survey.
Adding tags allows you to filter for surveys by their tag for better organization/search of your surveys.
