Users

Users in a web analytics report is the number of distinct identifiers that recorded at least one visit within the selected range, not the number of visits.

The basis for counting is an identifier written into a cookie or browser storage on the first visit and counted once for the whole range. Within any range the order of the three headline numbers is fixed: users is at most sessions, and sessions is at most pageviews; a report that breaks this order has a definition or a collection problem. There is also a tool collision that is often missed: the card labelled Users in GA4 is active users by default, meaning only people with an engaged session, whereas in most web analytics tools the same word means any visitor with at least one recorded view. Comparing user counts across tools without reading their definitions is therefore pointless.
