About the XML Sitemap

Google and other major search engines love the XML Sitemap, which means you also should learn to love it. This file tells crawlers what pages you wish to be crawled and at what frequency, which in turn tells them the priority and how regularly these are updated. The process to add one is simple: simply make the file using one of the many free XML programs available, then add the url in Webmaster Tools so the search engine in question recognizes it.
