I'm looking at this under Languages==>Configure, and wondering if I should leave the site with a default language of English, allowing users to choose their own languages (The "None" selection), or if I should go with the "Path prefix with default language fallback"?????
It's early enough in the course of this site being developed that I'm not too worried about breaking any links, but I am concerned about SEO.
If I choose the latter of the two choices above, will my default language have http://SLD.TLD/en/blah... or will it have http://SLD.TLD/blah and http://SLD.TLD/en/blah ???
I understand that with the paths German would be http://SLD.TLD/de/blah, etc., but if I choose none, will German simply be http://SLD.TLD/blah with the translated system content in German?
One of the big concerns I have is having more than one page with identical content, as I understand this isn't good for SEO. I've taken care of things like that in my .htaccess file to eliminate http://www.SLD.TLD, for example, but in any of the scenarios above, if any, will I be having duplicate links in the same language? i.e., http://SLD.TLD/en/blah and http://SLD.TLD/blah I realize that there would be at the very least (with Path prefixes) an http://SLD.TLD/ru/blah, and an http://SLD.TLD/de/blah, as well as at least one path for English.
