Our sitemap will be a valuable help in finding the information you are looking for. A site map, or simply map, is a web page that lists all the pages of a website hierarchically. Created to facilitate the user’s navigation throught the site, he then had considerable importance in the activity of scanning the network by the search engine crawlers.
As well as the simple sitemap also the XML sitemap is a list of links. Introduced by Google, and then also used by Yahoo! and MSN, allows webmasters to mention within an XML file, and not only, all the URL of the pages of a particular website that you want to submit to the search engine. In this way also dynamic sites can provide correct URLs allowing for more intelligent indexing.
