How a session is defined for Visitor tracking
We track both unique visitors and sessions separately. If you are using the Searcheo JS integration we already implement unique visitor id’s and session ids.
A visitor ID is intended to be used across sessions. If you are using the Event Tracking API directly then you can use your own Visitor and Session ID’s unique to your use case.
How long does a session last?
A session lasts for 30 minutes and then is regenerated automatically using the Javascript implementation.
