Automatically Collected Events include:

  • first_visit: the first time a user visits a website 
  • page_view:each time the page loads or the browser history state is changed by the active site
  • session_start:when a user engages the website, A session ID and session number are generated automatically with each session and associated with each event in the session
  • user_engagement:when the app is in the foreground or webpage is in focus for at least one second

Automatically Collected Events cannot be disabled, and do not count towards the 500 event limit.
