Welcome to the Q&A Forum

Thank you for your response! With Austrian/German IP I mean, that we planed to redirect the user IP wise. So if anybody comes to the site with an ip from Austria he should be redirected to the /at site If anybody comes to the site with an ip from Germany he should be redirected to the /de site Data comes from GeoIP Database. So you'r saying, that we don't need a main Home Site? How do the crawler know where to go? Best case would be to have domain.com/AT/ indexed in Google.at and domain.com/DE/ indexed in Google.de a) Language Meta would be the same for /AT and /DE because the language is german in both countries. b) Will check how this works c) What do you mean with update the content to mention the country and location? Content wise there won't be much difference. That's why im concerned about DC. The difference would be some headlines and the terms of delivery!

I definitely agree going down to one domain is a good plan and janmi is correct. You will want to make sure you redirect your specific language site to the relevant directory. In regards to increasing your rankings, focus on your on-page optimizations for each language. I am currently going through this myself and got some great feedback a couple weeks ago: http://www.seomoz.org/q/international-seo-3 In regards to tracking your success, use your analytics to track the increase of traffic per language with an advanced segment of non-paid search. Good luck!
