I thought this would be pretty simple but i can't really figure out how to use a query string to create a custom report.
I have multiple pages where all have a query string called
?platform=. There may be other query strings as well and "platform" may not be the first one.
All I want to do is to create a report where I can see all visits that has a page with the
?platform= query string as a landing page. Then I want to be able to click on each possible value of the platform parameter and get separate stats from that.
I guess it's very similar to the "search" query parameter feature but I already use that for search.
I also know I could create an custom event or a custom variable and track it that way but it feels a bit weird since it already is a parameter in the URL that Analytics knows about.
I've found some data in the "Behavior -> Path" metric but i can't really figure out to make Analytics treat is as a "filter" more or less so I can drill down into the the value of the query string.
