Best approach to make a localized website [closed]

Question

What's the best way to make a website localized to multi languages?

I'm working on a website, and our manager wants it to be like:

http://www.website.com - default to english http://fr.website.com - french http://de.website.com - german

He says it's good for SEO, some developers wants to make it based on cookie and user's accept-language, so the url would always be http://website.com but content would be based on cookie/accept-language.

What you think?

thanks!

This article appears to have a good guide to your question: http://www.antezeta.com/blog/domains-seo/

Essentially, they recommend localizing by TLD most, followed by Subdomain, followed by directories

Cookies are a bad idea because Google will not be able to index your localized content.
