Out of Beta and into the real world, international real world that is! Google has just announced adding a new section to Google Webmaster Tools, labeled “International Targeting”. If you operate a website that targets visitors from more than one country, and in more than one language then this may be of serious interest to you.
In an effort to respond to the public out-cry for help identifying issues with hreflang annotations (the markup that enables search engines to serve the correct language or regional variation of a page in order to provide more targeted results for searchers), Google offers webmasters a tool that makes note of two of the most common problems associated with language targeting and hreflang annotations:
Missing Return Links
The first issue Google helps identify is related to missing return links; if an annotation is not confirmed from the page it is pointing to, there will be an error. For example, if page A links to page B, then in-turn page B must link back to page A, otherwise the hreflang may not be properly interpreted by search engines. For each of these errors, Google identifies where and when detection took place as well as where the expected return link should be.
See the Example Provided by Google:
Incorrect Hreflang Values
The value of the hreflang attribute must either be a language code in ISO 639-1 format such as “es”, or a combination of language and country code such as “es-AR”, where the country code is in ISO 3166-1 Alpha 2 format. If the language or country codes are not in these formats then Google reports the issue and provides an example URL to assist with fixing the problem.
