This article is about Universal Analytics, which is going away. It's critical that you migrate your Universal Analytics property settings to Google Analytics 4, or you will begin to lose data on July 1, 2023 (July 1, 2024 for Analytics 360 properties). Learn how to migrate your settings.

Default channel definitions

See the rules that define each default channel.

The default system channel definitions reflect Analytics' current view of what constitutes each channel in the Default Channel Grouping. While these definitions may evolve as the market evolves, we provide the current definitions here for your information.

  • These channel definitions are case sensitive. When manually tagging URLs, use lowercase tags to ensure Analytics categorizes sessions correctly. For example, email campaigns tagged as Email do not match the system definition for the Email channel.
  • Not all dimensions allow Analytics to query associated cost data. If such dimensions are used within a Channel Grouping object, the cost data for the channel grouping can't be retrieved.
