Hi SaraSEO,

I don't think redirecting visitors based upon country is wise because of the following reasons:

• The Search Engine crawlers are not neccissarily located in the country they crawl for and might not be able to crawl all languages.
• Redirecting Users but not Crawlers could be considerd cloaking
• There might be German speaking people in sweden getting very annoyed not being able to see the german version. - Google explicitly advises not to do this:

"Make sure each language version is easily discoverable

Keep the content for each language on separate URLs. Don’t use cookies to show translated versions of the page. Consider cross-linking each language version of a page. That way, a French user who lands on the German version of your page can get to the right language version with a single click.

Avoid automatic redirection based on the user’s perceived language. These redirections could prevent users (and search engines) from viewing all the versions of your site."
