Google webmaster tool has enabled a new feature called "Set geographic target". This is extremely useful for sites with specific geographic target audience. Like a UK soccer site specifically for UK people can choose UK as country and improve their rankings on google.co.uk. You can find it under Tools-Set geographic target
I had a look at that myself earlier this morning. Its a pity that you can only limit it to one particular Geo target. It would have been nice if they gave you the option to geo target specific parts of your site for specific geo regions. Most of my sites are done in two languages, so it would have been nice to have targetted each language to a specific geo range. Maybe they might improve on this in the future, as I think it will be a useful tool for webmasters.
