Default Channel Grouping

We’ve implemented GA4’s Default Channel Grouping logic as a JavaScript function. While our implementation closely mirrors GA4's behavior, it may not provide exact matches in all cases. This is primarily because the BigQuery export does not include certain parameters that GA4 uses in its grouping logic, such as Source platform and Google Ads campaign type. As a result, discrepancies might appear between GA4 UI groupings and our classification.

Extra channel groups

In addition to the default channels, we’ve introduced a configuration option for custom channels via includes/custom/config.js

  EXTRA_CHANNEL_GROUPS: true

When enabled, this feature will generate new channel groups such as "Organic AI".
