BigQuery has an enormous benefit over GA4 customized stories as knowledge is rarely sampled, whereas in customized stories, knowledge might be sampled if there are greater than 10M events within the exploration report.

As a way to keep away from that and never distort your conversions knowledge, that you must exclude such domains from referrals so GA doesn’t provoke a brand new session.
At SEJ, for instance, we now have the brief hyperlink “sejr.nl” area, which needs to be handled as the identical area – so we added it to our exclusion checklist.
Additionally, when you have subdomains and wish to observe throughout subdomains utilizing the identical GA4 property, that you must exclude your individual area from referrals as a way to maintain the identical session when customers navigate from one subdomain to your fundamental area.
