A site map (or sitemap) is a list of pages of a web site accessible to crawlers or users. It can be either a document in any form used as a planning tool for web design, or a web page that lists the pages on a web site, typically organized in hierarchical fashion. This helps visitors and search engine bots find pages on the site.
By default your website does not have a site map. However it is fairly easy to make a site map for your website.
Adding a site map is not the only method for getting your site listed in search engines. Other methods for getting your site listed in search engines can be found in this knowledge base article -
