A Session is a defined quantity of visitor interaction with a website. The definition will vary depending on how Visitors are tracked. Some common visitor tracking methods and corresponding Session definitions:
- IP-based Visitor Tracking: A Session is a series of hits from one visitor (as defined by the visitor’s IP address) wherein no two hits are separated by more than 30 minutes. If there is a gap of 30 minutes or more from this visitor, an additional Session is counted.
- IP+User Agent Visitor Tracking: A Session is a series of hits from one visitor (as defined by the visitor’s IP address and user-agent, such as Netscape 4.72) wherein no two hits are separated by more than 30 minutes. If there is a gap of 30 minutes or more from this visitor, an additional Session is counted.
- Unique Visitor Tracking (cookie-based, such as Urchin’s UTM): A Session is a period of interaction between a visitor’s browser and a particular website, ending upon the closure of the browser window or shut down of the browser program.
