How do I get the full benefits of international SEO?

You need new beautiful URLs for each language and page that should be indexed by search engines.

The easiest way to get SEO for your translated sites is to have the language added as a sub domain like es.example.com for Spanish. This requires that you add those sub domains to your DNS server or use a wild card.

Use the following option in your SiteTran Widget Code on your site:

var sitetran.url_type = "sub.domain";

If you have access to your site's backend, you can add subdirectories like site.com/fr/ and return SiteTran's SEO optimized static translated pages for those requests.

If you're integrated via the WordPress plugin, you'll have the option to use subdirectories by default.
