A sitemap is a specific file which contains a list of all the pages on a given site. It allows both visitors and search engines to find content much easier, so it can boost the success of any kind of site. If visitors are looking for a specific page, the sitemap will help them to locate it and the enhanced user experience raises the chance for them to revisit this site eventually or to recommend it to other people. Search engines also look for a sitemap on every site they crawl as such a file allows them to index the content better and to track changes on various pages which will later be displayed in the search engine results, thus a sitemap can boost the ranking of a particular website. Considering that the number of sites keeps growing on a daily basis, having a sitemap is recommened if you would like your site to be more popular.
