In your Searchanise admin panel, go to
Integrations →
Google Analytics,
turn on the integration, and
apply the changes. Searchanise starts sending events to GA4 as soon as you turn it on. Event collection is automatic, but report setup is not. Some event details may not appear in GA4 reports automatically. If GA4 doesn’t provide a detail by default, create a custom dimension or metric for it. It can take 24–48 hours for the new definition to appear in reports.
The
help article has the full setup details and the complete list of events and parameters.
