If you use Google Analytics on your web site, you should update your tracker code that is placed in your code. The new tracker is faster, and offers added tracking functionality (See Google’s announcement)
New Code: (put your tracker ID in where you see the X’s)
var pageTracker=_gat._getTracker('UA-XXXXXX-X');
pageTracker._initData();
pageTracker._trackPageview();
While you are updating your code, you might also want to consider moving this and any other javascript to the bottom of your web site for improved performance.
