Google Translate

Google Translate is a free, multilingual statistical
 machine-translation service provided by Google Inc.
 to translate written text from one language into another.
Free Translation for Spanish, French, English, German,
 Portuguese, Russian and Italian languages.

One way of catering for the long tail of keywords
 is to ensure that each of your pages has a unique
title and, ideally, rather unique content as well.
Another is to add translations of your pages for a
multitude of languages, which will generate a
multitude of new ways to find you there are paid
online services to which you can submit a text file,
 and then pick the languages you want it to be
 translated into by native speakers.
