Are the following urls threated the same in SEO rank or is someone better than another? If, why?
language.example.com/pageexample.com/language/pageGoogle just announced New markup for multilingual content. This should make it easier for multi-language sites to deal with translated versions of their website.

You should decide which is best regarding its content, but the language in particualar to show you an example:

Before the domain seams to be the standard and I would recommend it!
Good luck!
