In web analytics, a session represents a single visit by a user to your website, encompassing all interactions made during that visit, such as page views, clicks, and transactions. A session starts when a user enters the site and ends either when they leave or after a period of inactivity, typically set at 30 minutes. This time limit can reset if the user continues interacting with the website. For instance, if someone uses Toolbird Analytics to monitor their website, they might observe that a user had a session during which they visited three different pages within 20 minutes. Pirsch would record this as one session, grouping all actions within that period under that single session. Sessions provide valuable insights into user behavior and the effectiveness of website content or interface. Website owners can analyze metrics such as the number of sessions per day, average session length, or pages per session to make informed decisions about their site.
