Definition
A session is a collection of pageviews, clicks, engagement signals, and events from a visitor during a continuous visit.
Meaning
It helps teams analyze behavior as a visit, not as isolated page hits.
Why It Matters
Session counts show how much traffic is available for UX analysis and whether behavior patterns have enough volume to trust.
History And Context
Session-based analytics became common with early web analytics tools because marketers needed a way to group many page requests into a single visit.
