This comScore data was put out a couple hours ago:
Globally the search market increased its query volume by 46% from a year ago. The US saw query/volume growth of 22%. Russia, France, Brazil and Japan were the top growing markets where volume increases ranged from 48% to 92%.
Roughly 53% of Google’s revenues come from outside the US; however, those numbers should climb because most markets outside the US are less mature (save the UK) from an advertising perspective. Ad dollars will follow consumer growth.
