I need to track an intranet site's traffic and would prefer to use Google Analytics because we have several other properties already being tracked there.
Google Analytics requires a public address to set up a new property for tracking. If I create a subdomain (intranet.domain.com) to satisfy that requirement, I believe the rest should work fine. (External .js file for Google is outbound-reachable from within our network, inbound-external access is blocked to protect confidential information.)
Thanks!
Google Analytics records data via parameters on tracking pixel requests. You need to make sure that requests for google-analytics.com/__utm.gif will go through from your intranet. (I'm guessing it shouldn't be an issue since you said google-analytics.com/ga.js is not blocked.)
It's also not a problem using the web property ID ('UA-xxxxx-x') on different domains than it was originally created for.
