Google Analytics includes a function you can use to track outbound links. This function essentially rewrites a link as the page you specify. Continuing my example above, if I wanted to track my Feedburner subscription link using Google Analytics, I would simply add the following JavaScript in my link (<a> tag):
onClick="javascript
: pageTracker._trackPageview('/subscribe.php');"
Whenever someone clicked on that link, Google Analytics would log that click as a visit to the virtual page "subscribe.php". To use this feature, you do need the latest version of Google Analytics.
