New sample shows how to use the free GeoIP service to find the location and show the lat/lon of the visitor on a map. Here is the link to the sample : http://sathyaprasad.appspot.com/geoip.html
If you go to my homepage http://sathyaprasad.appspot.com you can see how I have used the smaller version of the sample inside of a page using an iframe to locate the website visitors. Feel free to copy the code and use it in your site.
