Group Key

A group key is the property name that defines the grouping type in group analytics — such as company_id or workspace_id — specifying the basis on which users roll up to an account.

A group key is what tells the system 'count these as one'. Its importance shows when a user can belong to several group types at once: a person can be seen under both a company key and a team key, and each key builds a different aggregation view. Choosing a key is a modeling decision, not a technical detail: define it poorly — an email address instead of a stable company ID — and the groups break when the data changes and the account trend becomes meaningless. A group key only means something in tools that have a group call and a known-user model; in plain web analytics there is no such concept.
