Today Google announced that Google SiteMaps now supports mobile website. This new extension, called Google Mobile SiteMaps, allows mobile website webmaster to submit their mobile website URL. Mobile phone users can also search through these, and other mobile-friendly websites, using Google Search for the Mobile Web.

Google SiteMaps is a program that lets webmasters inform Google quickly about new or updated web pages, and boost Google index coverage and speed up the discovery and addition of their web pages.

If your site has dynamic content or pages that aren’t easily discovered by following links, you can use a Sitemap file to provide information about the pages on your site. This helps the spiders know what URLs are available on your site and about how often they change.

A Sitemap provides an additional view into your site (just as your home page and HTML site map do). This program does not replace our normal methods of crawling the web. Google still searches and indexes your sites the same way it has done in the past whether or not you use this program. A Sitemap simply gives Google additional information that we may not otherwise discover. Sites are never penalized for using this service. This is a beta program, so we cannot make any predictions or guarantees about when or if your URLs will be crawled or added to our index. Over time, we expect both coverage and time-to-index to improve as we refine our processes and better understand webmasters’ needs.
