I'm working on a site that has quite the backlog of Google Analytics data for their site network. One of our big questions is whether people enter on one site and move to another (and if so, of course, how do these visits differ from single site visits).
The hostname report (Audience > Network > Hostname) shows all the host names and I've setup Advanced Segments to get site-specific data. That all works great, but I'm really having a hard time figuring out how to find visits to multiple sites as defined by visiting more than one subdomain or the root site and one or more subdomains.
I do see that other hostnames somehow come through when I apply one of the segments to the host name report. Which I can't say I expected. Is that the best way to see if people are visiting 2+ sites?
