I'd like to star with you this section, based on the Web Analytics myths that once or another we get to listen. One of them, is, of course: The _setMaxCustomVariables option.
If there's a Google Analytics feature that any CRO expert must master, it is Custom vars. With them we are able to track the specific info we need from our visitors: Visit purpose, demographic info, section visited,etc...
Unfortunately we only have 5 of them.
Here comes the discovery of the existence of a "bug" or forbidden feature, the _setMaxCustomVariables option by Ophir Prusak.
What do you think: Myth or true?
Let's the experiment!
When debugged: we have NO errors and the variables ar actually setup (even it's stored in the _utmv cookie if it's Visitor's level custom var).
So, as Ophir discovered... We can save this info. It works.
The problem is that we can not retrieve it...
No way i found: GA interface or API via Excel.
So.... it's true, it works... but you'll never use it.
Did you ever get to use it in the old GA interface?
