Understand Sessions in context.
Simply explained explanation
A group of website or app interactions during one visit.
Professional explanation
GA4 session count, generally initiated by a session_start event; one person can have multiple sessions.
Analytical explanation
Session shifts can come from acquisition mix, redirects, cookie persistence, consent or tracking changes. Compare the same channel grouping and timezone.
Technical explanation
GA4 Data API: sessions. In event-level data, session identity commonly combines user_pseudo_id and ga_session_id; naïve distinct ga_session_id alone can miscount.
