The XML Sitemap user control creates an XML site map in accordance to the http://www.sitemaps.org
specification. The control provides two basic properties for
customizing the pages included in the site map:
1. Include pages for which anonymous access is denied
2. Include pages for which indexing has been disabled
The XML Sitemap can be manually submitted to Google, Yahoo!, Windows Live and Ask.com to allow your website to begin ranking within these search engines.
