Thanks for the link

To make all of your site's content more crawlable, avoid automatic redirections based on the user's perceived language. These redirections could prevent users (and search engines) from viewing all the versions of your site. And last but not least, keep the content for each language on separate URLs - don't use cookies to show translated versions.

  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
