Every tool i've downloaded and used checks the US search engines for keyword ranking, etc. Are there any tools that check the top UK search engines instead, ie. uk.search.yahoo.com and google.co.uk
These tools should let you set the google data centers. I have also used this link -> http://www.seoserp.com/web_tools/google_top_1000_serps_checker.asp sometimes to check country specific SERPs (uses java).
