On October 22, 2024, Google Analytics 4 (GA4) rolled out an update to improve users’ ability to analyze traffic sources through its BigQuery export feature. This update brings in new session-level traffic source fields, allowing businesses to view user interactions across various channels better. With these new capabilities, GA4 users can better understand where their website visitors are coming from, how different marketing channels contribute to user engagement, and how these sources work together to drive conversions.
What’s New in GA4’s BigQuery Export?
The latest enhancements in GA4 BigQuery export automatically add new session-scoped traffic source fields, making it easier for users to dive deep into channel performance and cross-channel attribution. By default, these updates apply to all existing BigQuery exports, meaning current GA4 users don’t need to do anything to benefit from these new data points. Now, analysts can explore detailed insights without manually setting up or changing configurations.
Some of the key elements introduced in this BigQuery export update include:
- Session-Scoped Traffic Source Dimensions: These fields offer data tied to a user’s session, such as source, medium, and campaign. By using these fields, businesses can see which channels lead to engagement.
