Hello,
I am looking into using http://www.asual.com/jquery/address/ , but I am wondering how it effects google analytics. Google analytics is a snippet of code at the bottom of pages. I would imagine deep linking would still look like activity on the initial page, not new pages.
From what I can see it will look to google analytics like navigating to a new page.
Just open e.g. http://www.asual.com/jquery/address/samples/tabs/ and check the requests FF makes (e.g. with Live HTTP Headers) and you will see that the google analytics fires a request for every tab you switch to.
As long as the page, and the analytics code is being loaded, it will still count as a hit on the page. I don't think there would be any negative impacts of using this plug in.
in it's current version 1.3 the jquery address plugin tries to do the ga tracking automatically, using the asynchronous ga tracking (see http://code.google.com/apis/analytics/docs/tracking/asyncUsageGuide.html). this is also mentioned in plugin's api docs at http://www.asual.com/jquery/address/docs/#api-reference (look for $.address.tracker)
actually this new behaviour (i was using address' version 1.0 before) broke my custom tracking code on an ajax site - as it isn't configurable, i had to downgrade to 1.0.
