Tags allow you to see results by certain characteristics that some but not all of your users have, such as those who are car drivers, or users who manage others.
Use our Tags filter if you want to quickly assign a small number of users to particular segments. (If all or most of your users have one of the characteristics you want to segment your data by, for instance role type, then consider creating a Custom Attribute )
The Tags filter can be used when some users are part of a particular segment or have a particular characteristic. Users can have multiple, unrelated Tags (or no Tags).
You can use Tags if you want to be able to see results of, for instance, Car drivers, Happiness Champions, or Manage 5+ (people who directly manage five or more employees).
