Tracking Click-Throughs from a Specific Subdomain

[roblucas]

Hi,

I'm having quite a few problems doing something which I originally assumed would be quite simple:

I have one main site, and several affiliate sites which are on subdomains of the main site. So far, I've had a distinct GA profile for each site, with all sites on the same GA account.

The problem is that I need to track click-throughs from a specific subdomain to specific pages on the main site.

In order to do this I first set up a Goal on the main site's profile, with Step 1 as the the starting URL on the subdomain and assumed that I would be able to track click-throughs from the subdomain using only this. The problem with this was that GA doesn't by default distinguish between domains and subdomains, so the stats that I was getting weren't very useful.

So... The next step was to get GA to recognise pages from subdomains as different from those on the main site. For this, I used the standard bit of Javascript that Google provides here - http://www.google.com/support/analyt...?answer=27268- (_udn="example.com") to tell GA to track the domain names as well as the file paths. And added the advanced filter stuff as Google specifies (though they don't specify all possible options so there is margin for error here):
Filter Type: Custom filter > Advanced
Field A: Hostname
Extract A: (.*)
Field B: Request URI
Extract B: (.*)
Output To: Request URI
Constructor: $A1$B1

Around the date where I introduced these changes, I can now see GA data for /normal/style/paths drop to zero, and get replaced by data for www . full-domain.stuff/with/paths/like/this .

I then set up a new goal with step 1, again, as the page on the subdomain from which I want to trace click-throughs, and the following steps as the pages on the main site "funnel" that I want to use.

But I'm getting absolutely no data appearing in this Goal!

I've tried leaving it a couple of days for the data to start coming through, and also doing some click-throughs myself from a non-filtered IP address to make sure that there would be some data, but nothing is showing.

Anyone got any ideas about what is going wrong here, or similar experiences?

Unfortunately the Google documentation on this kind of thing is pretty skimpy.. It would be nice to be able to understand how advanced filters etc work as well.

Thanks,

Rob.
