Automatically collected events are triggered by basic interactions with your app and/or site (as indicated under the event name in the table below). As long as you use the Google tag or the Google Analytics for Firebase SDK, you don't need to write any additional code to collect these events.
Analytics collects events for Android and iOS apps unless otherwise stated. The names and parameters of these events can be helpful when accessing your raw event data in BigQuery.
To understand each event parameter listed below and how each parameter updates a dimension or metric in Google Analytics, see Google Analytics event parameters.
Note:
The following are several of the parameters that are collected by default with every event, including custom events:
- Web stream:
- language
- page_location
- page_referrer
- page_title
- screen_resolution
- App stream:
- app_version
- firebase_screen_id
- firebase_screen_class
The value assigned to event parameters must be 100 characters or fewer. The page_title parameter must be 300 characters or fewer. The page_referrer parameter must be 420 characters or fewer. The page_location parameter must be 1,000 characters or fewer.
If you override the page_location parameter, make sure that the URL path is valid. If you assign an invalid URL path, the Page location dimension will be empty. You can use the Campaign URL Builder to check whether a URL path is valid.
The firebase_screen_id and firebase_screen_class parameters are automatically collected unless you disable screenview tracking.
