This contest entry by Kyle Phillips is a utility class for dealing with google analytics. If you haven't messed with google analytics I suggest you give it a try.

I usually find myself adding google analytics code in a very hacky way... usually because the client asks for it at the 11th hour. Using a class like Kyle's would enable you to simply add the tracking code from the start and then if the client doesn't ask for it... you can just keep the class disabled... or charge more when you offer google analytics tracking for "phase 2" of the project

Hi!
I often use :
navigateToURL(new URLRequest(”javascript:pageTracker._trackPageview(…
To deal with analytics.
I think ExternalInterface with its Synchronous communication could slow the code execution when you track a page.
But with navigateToUrl you can loose some information when to call start at the same time :
[..]
navigateToURL(new URLRequest(”javascript:pageTracker._trackPageview(“the-first”);
navigateToURL(new URLRequest(”javascript:pageTracker._trackPageview(“the-second”);
[…]
“the-first” is never called.
It’s possible to use Timer or Enter_Frame to make delay but it’s not very well.
Do you have feedback with ExternalInterface Performances?
Google also provides a class of their own:
