I have a Google Analytics view that combines traffic to multiple subdomains. It has an advanced filter set up to view full page URL in reports.
As expected when using this filter, when I go to Behavior | Site Content | All Pages and click a link for any page, the link doesn't work.
The reason it doesn't work is that GA concatenates my view's "Website's URL" value with the full page URL provided in the report. For instance, if "Website's URL" is set to
https://www.example.com/ and I try to navigate from the report to a page with full URL
sub.example.com/page, GA opens a popup with URL
https://www.example.com/sub.example.com/page - obviously, this returns error 404.
I thought I could solve this problem by leaving "Website's URL" blank, but GA doesn't allow leaving it blank. Instead, it requires that Website's URL is a valid URL without parameters.
I hate fixing links opened from All Pages so much that I'm ready to write a simple redirect service for the links to work (e.g.
https://www.example.com/redirect-service/https://sub.example.com/page would redirect to
https://sub.example.com/page). However, that would force me to specify the URL of the redirect service -
https://www.example.com/redirect-service/ - as the value of "Website's URL".
Here's the question: does GA only use the value of "Website's URL" for navigating to pages from reports, or is there another use of the setting? Would I corrupt my view by setting "Website's URL" to the redirect service?
