If you want to rank translated web pages and you’ve translated your pages using Google translate or other machine translation tools, you may affect your rankings and contravene Google’s own Webmaster Guidelines, according to Google themselves.
Here’s a direct quote from the Google Webmaster Central Forum:
“…using automated translation tools to directly create content for your site could be seen as creating auto-generated content, which would be against our Webmaster Guidelines.”
