How does google analytics deal with source UTM and referral conflicts?

Question

How does google analytics deal with source UTM and referral conflicts?

For instance if i have a link like this http://example.com/?utm_source=test hosted on a 3rd party site, if someone visits that link, would the visit show up in Google Analytics as source = other / test or source = referral 3rdparty.com?

Or would Google analytics deal with this in some other way?

Answer 1

UTM information in the URL overrides referral in Google Analytics (Universal Analytics). At least if you fill the 3 required fields: utm_campaign, utm_source and utm_medium.
