Self-referrals and traffic source
I am using cross-domain tracking for several domains. I included all domains in the referral exclusion list, because a visitor should not trigger multiple sessions when there should only be one.
Unfortunately source traffic from the excluded domains is categorized as "direct/none". This makes it impossible to find out which domains refer to one another.
How can I configure GTM and/or GA so that the domains show up as source without adding extra sessions?
Re: Self-referrals and traffic source
You need to add these settings in GTM for your analytics tracking tag under More Settings -> Fields to Set:
Field Name: allowLinker, Value: true
Field Name: cookieDomain, Value: auto
You also need to add each domain to the Auto Link Domains field.
Hope this helps.

Thanks for your answer.
I feel ashamed for not setting these two parameters. After almost a year I noticed I forgot to set the allowLinker en cookieDomain parameters in GTM version 2. What are the consequences?
