You can add anchor tags. I use this on my site so that I can track with Google Analytics what people are visiting on the page.
I just add an anchor tag and then the part of the page I want to track:
var trackCode = "/#" + urlencode($("myDiv").text());
window.location.href = "http://www.piano-chords.net" + trackCode;
pageTracker._trackPageview(trackCode);
