/*
For example, to log every click on a particular link to www.example.com as a 
pageview for "/outgoing/example_com" you would add the following attribute to the link's tag:

<a href="http://www.example.com" onClick="javascript: pageTracker._trackPageview('/outgoing/example_com');">

It is a good idea to log all of your outbound links into a logical directory structure as shown in the example. 
This way, you will be able to easily identify what pages visitors clicked on to leave your site.
