I have a website, let's say
example.com. We have recently launched a new product and set up a new site in the same domain,
newservice.example.com, and have added a prominent link on the existing established site. Both sites are on the same Google Analytics account, but are set up as different properties.
How can I track, using Google Analytics, how much of the traffic coming to
newservice.example.com comes from the other site? I thought that they would show up in the "Acquisition" section as "Referrals", but when I go there, I see that 90% of the traffic of the new site shows as "Direct", which makes no sense (it's a new site and we haven't advertised it heavily). The "Referral" section doesn't show any traffic either coming from
