Event property definitions

  • Updated

By default, Amplitude tracks the event properties listed in the table below automatically, as they relate to page-viewed events. Some are tracked via client-side SDKs, and others, like Event Day of Week or Session Replay ID, are generated by Amplitude.

All these properties will be prefixed with amplitude_logo.png whenever you encounter them in Amplitude. If you prefer, configure Amplitude's SDKs to disable automatic tracking of these properties:
