Multilangual sites.

how to rank good for all languages?

[AcsCh]

I run a multilanguage portal of a small town and have some troubles to get it in ALL Languages to rank well. If I put the main page in Spanish, english drops, if main is english, spanish drops for the most interesting keyword, the townname.
How do google,yahoo define languages? I feel the "language meta" serves as much as nothing.
Any hints how you handle that?

I would do something like this:

domain.com - English
domain.es - Spanish
domain.cn - Chinese

That gives the SEs nice delineation of your sites by language and can be helpful when promoting on language specific directories and SEs.
