Have a lot of client sites that use a similar system of their primary domain with an external checkout software hosted elsewhere. Their analytics is filled with self-referrals from the primary domain. For example.
I have a primary domain in which I have entire control. This has a Google Tag Manager implementation using Universal Analytics. The secondary domain, a booking system, uses classic analytics.
I have no control over how the analytics on the booking system is implemented (aside from setting the tracking ID), but the developers say it is setup to use cross-domain tracking. Their implementation has:
_gaq.push(['_setAccount', 'UA-67867867-1']);
_gaq.push(['_setDomainName', 'www.seconddomain.com']);
_gaq.push(['_setAllowLinker', true]);
_gaq.push(['_setCookiePath', '/properties/abcd']);
_gaq.push(['_trackPageview']);
_gaq.push(['_cookiePathCopy', '/reservations/abcd/']);
My understanding is I need to configure GTM to mirror these settings as per the "Inconsistent Tracking Code Configuration" directions at: https://support.google.com/analytics/answer/3198398?hl=en
In GTM, "Allow Linker" is set to true. "Auto Link Domains" has "primarydomain.com, seconddomain.com", but this seems pointless as GTM is not on the second domain. "Cookie Domain" is auto.
Self-referrals still happen. What am I missing?
