I have found something interesting, I have my website in other languages using subdomains, for example, es.domain.com
And in all subdomains, in webmaster tools I have this warning:
HTML Improvements Last updated Jul 4, 2013 We didn't detect any content issues with your site. As we crawl your site, we check it to detect any potential issues with content on your pages, including duplicate, missing, or problematic title tags or meta descriptions. These issues won't prevent your site from appearing in Google search results, but paying attention to them can provide Google with more information and even help drive traffic to your site. For example, title and meta description text can appear in search results, and useful, descriptive text is more likely to be clicked on by users. More Information

The main domain is the only that don't have this message
Someone told me that I can add a code in the websites saying that belongs to same site but they use different languages. How can I do that? Anyone knows and can explain to me how to do it? :-)
At this part will be solved!
Thanks
