Today Google Translate has gone on-line. The new system from the search giants is available as a small snippet of HTML & Javascript code which can be placed on almost any web-page. The result is a translation of the page to any of the following languages:
Afrikaans, Albanian, Arabic, Belarusian, Bulgarian, Catalan, Chinese (Simplified),Chinese (Traditional), Croatian, Czech, Danish, Dutch, English, Estonian, Filipino, Finnish, French, Galician, German, Greek, Hebrew, Hindi, Hungarian, Icelandic, Indonesian, Irish, Italian, Japanese, Korean, Latvian, Lithuanian, Macedonian, Malay, Maltese, Norwegian, Persian, Polish, Portuguese, Romanian, Russian, Serbian, Slovak, Slovenian, Spanish, Swahili, Swedish, Thai, Turkish, Ukrainian, Vietnamese, Welsh and Yiddish.
You should consider however that only standard text will be translated. Text in images and flash movies won't be translated. In order to support these elements as much as possible remember to add well worded alt tags to your images and titles to your links. You can find out more about alt tags and title tags as well as best practise for managing images on websites with the Understanding Search Engines SEO Training tutorials.
