If Capture Organic Sources is enabled and UTM parameters are missing, Invoca fills in the referral domain instead — and out-of-session calls may show no UTM data at all.

Answer

If the “Capture Organic Sources” setting is enabled in your Invoca Tag configuration, then whenever UTM parameters are missing, utm_medium is set to “Organic” and utm_source is set to the referral domain instead. Out-of-session calls may also show no UTM data. Repeat callers are a common example of an out-of-session call — such as a caller dialing back from a previously saved number. Invoca also identifies out-of-session calls by checking for duplicate Invoca Unique IDs, which are assigned to indicate a single web session.
