A sitemap is normally known as a file of the XML type which has the function of listing the URLs for any site. The sitemap allows the webmaster to add further information about the URL such as the last updates, the changes in the URLs and how often it is made, and also the importance of the URL in relation to the others. Sitemaps can prove to be beneficial in certain situations such as the inability of the user to access every area of a particular website through the interface of a browser.
