Sessionization
Definition
Events are grouped into related visits or sessions according to defined rules.
The rule-based grouping of individual events into analytical sessions based on identity, time, and domain rules. The result depends on timeout, event order, and device or user assignment.
Simply explained
Multiple clicks are assigned to one visit; a longer pause can mark the start of a new visit.
Why it matters in practice
The term improves reliable access to data and knowledge as well as their usable linkage in digital systems.
Example from business
Page views with no more than 30 minutes of inactivity are grouped into one session.
Limits and pitfalls
- Treating a 30-minute timeout as a natural law, ignoring delayed events, parallel devices, or identity changes, or equating an analytical session with an authentication session.
Origin & history
Sessionization originates from web analytics, log processing, and event-based data processing.
Use in mid-sized companies
