Thanks.

That is very helpful. I have 3 different types of links from the main site to the subsite.  2 of them are addressed in the article but the third is not.  Do you have any suggestions?

1. Links from the menu on the main site to subsites ==> We need to add the  onclick="_gaq.push(['_link', ... to enable the cross site tracking.
2. Play picking during play confirm ==> We need to add onsubmit="_gaq.push(['_linkByPost', this]);" to our postback on the page.
3. Play picking using 302 redirect when the play.aspx request page is loads ==> Here it's not clear what we should do to handle the cross site tracking when a user is moved from site to site using an http redirect.  (The 302 redirect is being implemented because for business reasons we need to redirect users to different sites based on their location and we don't want Google to think we are being manipulative)

I currently have one main .com site and am planning on launching geo-location subsites .co.uk, .com.au, .ru, etc...

Traffic will flow between both sites and some of the content on the subsites will be duplicate and therefore include a canonical tag to the main site.

I want to set up GA to capture who is going to the subsites and vice versa and correctly capture crossover traffic.  Any advice on implementing advanced analytics directly (or links to sources that will direct me the right direction for this project)
