We are currently in the process of loading google analytics on our website.
The question came up as to best strategy for tagging our domains and sub-domains, as our first attempt was to create unique tracking codes for each sub-domain, such as one for Admissions, one for Financial Aid, one for the Registrar's Office, etc.
Further readings from both Kyle James and Google own blog suggest that a better way might be to use one code for the primary university domain, use it to cover all of our sub-domains, and then use profiles to limit the reports for each unit, ie Admissions, Financial Aid, and the like.
Do you see any problems with the approach?
The thinking from our IT guys is that this is something we may not want to do, as everyone will have access to everyone else's data (can we restrict access to profiles by groups). The web guys like it because we can track sessions between domains, which is something we haven't been able to do (like tracking a prospective student on the Admissions site when they investigate cost of attendance data on the Financial Aid site).
Any advice from those of you who have been there and done that.
