I believe seologs has a tool that can show your position in google for a specific keyword across multiple data centers.
I am not sure if I know how to use this site. I have registered and signed-in. The only other thing that I can do is to submit my site URL. I have no access to any other features stated in the main page.
This is a pretty straight-forward tool. It will track your sites ranking for the list of keywords that you input. The only thing I see as a negative is that it only shows if you are in the top 100 for that kw. Will run a couple of my sites thru it and see how well it performs. Thanks for putting it on the forum.
