"Key-values" are core DFP features that allow you to set information about the user or his context to each page view and target campaign. Examples of key values:
- UserType (guest, authorized)
- Page type (category index, article, feature etc)
- Content category ([sports, football], [politics, USA, Trump] etc)

For particular key-values, an inventory check will give you some insights, although it does not show how many users are in the target group.
