Hello,
I have one domain for my website (www.domain.com) where I receive all the new traffic and a subdomain (billing.domain.com) for the billing system.
Im tracking both in Analytics.
I have a goal (new order) configured in the subdomain -billing system-.
But when I want to track the source / medium of the goals (new orders) in billing.domain.com, always appears my main website (www.domain.com) as the referral.
Now I added in Analytics: Admin > Property > Referral Exclusion List, the www.domain.com and domain.com.
Do you think that now I can track the real referrer of the goals?
Or should I do a more complex tracking setup with Tag Manager ( https://support.google.com/tagmanager/answer/6106951 ) to pass the session cookies from a subdomain to another one, just to identify the real source / medium of the visitor?
Thank you
