Visitor ID vs Client ID[ Edited ]
May 2016 - last edited May 2016
Is "Visitor ID" the same thing as "client ID" in Google Analytics?
I understand the concept of client ID and user ID, but don't know what "visitor ID" means in my reports. Could you please explain it and how it relates to client ID or user ID?
Re: Visitor ID vs Client ID
Your VisitorId referenced here is a custom dimension. That is, someone configured and named it "visitor ID" in the Google Analytics admin property setting and then passed what appears to be a session id, into the GATC (Google Analytics Tracking Code) as a value to be placed in the custom dimension of that index.
In other words, this is not normally available, built in dimension -- someone specifically created it.
