this is informative tool, it provides the lots of information like Location searching, Opportunity, Local Monthly Searches, Suggested Bid, Competition.
Thanks for informing about this tool, it is really beneficial and it tells everything about the competition.
Shame google makes it so difficult to rank in multiple countries when you have a product for sale that is of interest to all. The server location is almost always the factor. So as a result you have to pay for adwords to compete in those markets or create a TLD for that location.
