Why is source / medium not getting tracked on Google Analytics?

First, make sure your Google Analytics code has been added to VYPER. This document helps you with that.

There's a few ways to make sure you can see source / medium.

1 - You have to set-up cross-domain tracking (tracking either VYPER's domain or your subdomain) to track medium and source, otherwise, GA reports it as a referral.

Here's a help doc for you:

2 - Set up VYPER as an exclusion URL. 

3 - View a secondary dimension (gif below shows you how to do it).

Notes

1. You can see source / medium referral traffic without setting up cross-domain, see documentation.
2. If still want to set up cross-domain tracking, we recommend doing it using Google Tag Manager.
