Have you ever experienced the Google analytics for your google knol? Recently i have experienced it and really amazing. I don't have such experience before.
After you complete your new knol, you click the "edit my preference" button. Then click on the "Analytic" tab. Here you get a box named "Tracking Code". Now put your site in the Google Analytics fresh and from there you get a tracking code value. Just add it to this box and observe the result within 24 hours.
