From Facebook Developer Wiki

To make your app's clicks show up in Google Analytics, do you have to create a new Website Profile in Google Analytics with the domain "apps.facebook.com"?

When Facebook sends the __utm.gif tracking image to Google Analytics, the "utmhn" request parameter is set to "apps.facebook.com".

Is it possible to use the _uff flag to allow more than one Google Analytics account? I don't see a method to do this in the documentation for fb:google-analytics

When embedding the javascript directly, it would look like:

 _uff = false; // Reset for second account

[edit] new code ga.js

any plans for using the newer style ga.js?

Would be very interesting to implement ga.js instead of urchin.js!

[edit] can this tag be used on facebook pages ?

it says tag is restricted to facebook canvas. im new to this terminology, does this mean it cant be used on a facebook fan page? and if not why not?
