Why Export GA4 Data to BigQuery?
Exporting GA4 data to BigQuery gives full access to raw analytics data and removes major GA4 interface limits. Setup is free and storage cost is very low, and a site with about 30,000 sessions per month can store data at no cost. Raw exports avoid sampling that starts when requests exceed 10 million events and avoid cardinality limits that group values under Other. Data retention is unlimited in BigQuery, while GA4 interface user and event data can be limited to 14 months in segmented reports and explorations. The export also allows deep customization, custom sessions and attribution models, and easy joins with ad, search, and CRM data, but it only collects data from the day the link is created.
