Region support and multi-regional sites
Global companies might choose to publish content, and offer products or services specifically for certain regions. While today a language can be detected, there is no technical solution available to detect a region.
In this context we need to distinguish between the various regions; in this context the term 'region' is sometimes used synonymous with 'country'.
Internet search engines also find that location or region specific metadata is not reliable enough to use it for region detection. Consequently crawlers expect the URL to carry region specific information. The most obvious is the top-level domain name carries the country code and thereby the region information. For example, a domain name such as xyzco.fr or xyzco.co.jp strongly indicates the company resides or operates either in France or Japan.
If top-level domain names are used, no further action is required to allow region identification of that website. However, for more generic domain names such as .com or .eu , additional steps are required for enablement. In such cases encode the region information in the URL, and pair it with tools provided by Internet search engines, such as Google Webmaster Tools for Geographic Targeting.
