Event property definitions

By default, Amplitude tracks the event properties in the following table automatically for page-viewed events. Client-side SDKs track some properties, while Amplitude generates others, like Event Day of Week or Session Replay ID.

Amplitude prefixes these properties with the Amplitude logo in the application. To disable automatic tracking of these properties, configure Amplitude's SDKs.
