This javascript tracks clicks on individual links as Events in Google Analytics.
The link the user clicks on will be identified by the URL, Anchor Text & ID (link number).
You have to use the Google Analytics Asynchronous Tracking for this script to work:

The script must be placed just after your standard Google Analytics script (between and ).
The script loads as soon as the DOM has loaded using addDOMLoadEvent:
