Tracking traffic from a redirect URL
I am new to using a more detailed version of GA. So I was wondering if I have an existing webpage: www.abc.com/page1, but I am implementing a new URL (www.123.com) that will redirect to www.abc.com/page1. How do I setup up my analytics to track the traffic that is only coming from www.123.com? Thanks in advance!
Re: Tracking traffic from a redirect URL
It depends on what kind of traffic you are sending to 123.com and whether or not the originating traffic is coming with utm parameters and how you implement the redirect.
If you simply do a redirect you'll probably see all traffic from 123 to abc as a referral traffic source. This may not be desirable.
If you market 123.com at all you'll want to configure the server to pass parameters and from there you can add a custom param such as redir=123.com and or set document.referrer as a session level custom dimension. There are more many many ways to do this.
