In December 2011 we announced annotations for sites that target users in many languages and, optionally, countries. These annotations define a cluster of equivalent pages that target users around the world, and were implemented using rel-alternate-hreflang link elements in the HTML of each page in the cluster.
Based on webmaster feedback and other considerations, today we’re adding support for specifying the rel-alternate-hreflang annotations in Sitemaps. Using Sitemaps instead of HTML link elements offers many advantages including smaller page size and easier deployment for some websites.
To see how this works, let's take a simple example: We wish to specify that for the URL http://www.example.com/en, targeting English language users, the equivalent URL targeting German language speakers http://www.example.com/de. Up till now, the only way to add such annotation is to use a link element, either as an HTTP header or as HTML elements on both URLs like this:
<link rel="alternate" hreflang="en" href="http://www.example.com/en" >
<link rel="alternate" hreflang="de" href="http://www.example.com/de" >
As of today, you can alternately use the following equivalent markup in Sitemaps:
<url>
<loc>http://www.example.com/en</loc>
<xhtml:link
rel="alternate"
hreflang="de"
href="http://www.example.com/de" />
<xhtml:link
rel="alternate"
hreflang="en"
href="http://www.example.com/en" />
</url>
<url>
<loc>http://www.example.com/de</loc>
<xhtml:link
rel="alternate"
hreflang="de"
href="http://www.example.com/de" />
<xhtml:link
rel="alternate"
hreflang="en"
href="http://www.example.com/en" />
</url>
Briefly, the new Sitemaps tags shown in bold function in the same way as the HTML link tags, with both using the same attributes. The full technical details of how the annotations are implemented in Sitemaps, including how to implement the xhtml namespace for the link tag, are in our new Help Center article.
A more detailed example can be found in our new Help Center article, and if you need more help, please ask in our brand new internationalization help forum.

Organization | Anchor Text Examples | User Friendliness | Anchor Text Behavior |
The Mosaic Project | Work for Mosaic Order Our Curriculum Guide Outdoor School | High: Users can get an accurate idea of the content on the links’ destination pages just by reading the anchor text. | Active verb phrases and rich nouns accurately describe the pages that the links are pointing to. |
Asian Liver Center | Learn more here | Low: The anchor text is too generic and does not give users an idea of what the linked-to content is. | Generic phrases give little insight into the pages that the links are pointing to. |
Organization | Page Title Examples | User Friendliness | Page Title Behavior |
VAMS International | Upcoming Events | VAMS International Request Service | VAMS International FAQ’s | VAMS International | High: Each page’s content is relevant to its title, and the user can get a good idea of each page’s unique offerings and functionality. | Concise, rich language joined with the organization’s name accurately describes the corresponding pages. The titles show how each page is unique while also acknowledging that they are all associated with one organization. |
MHCD Evaluation and Research | MHCD Evaluation and Research | Low: This site contains a lot of diverse content and rich functionality; however, the uniform page titles do not convey these strengths. | This page title is too general and does not accurately describe the content on each page. The same title is used across all the pages on this site. |
