Google Targeting Languages

How to Target a Specific Google Domain – in Multiple Languages

Google rankings change based on the Google domain you search on. These domains mostly represent countries or regions (e.g. Google.cat = “Catalonia”) in their according language. Currently there are about 200 different Google domains.

Usually you would assume that search queries in Google.co.uk are typed in English, in Google.fr in French, and so on. Therefore, a common goal is to optimize a page for a specific market in one language.
