A sitemap is a special file which contains a short list of all the web pages on a given Internet site. It allows both visitors and search engines to discover content much easier, so it will boost the success of every Internet site. If visitors are trying to find a particular webpage, the sitemap will help them to find it and the improved user experience raises the likelihood for them to come back to the site later on or to recommend it to other people. Search engines also search for a sitemap on every single website they crawl because such a file makes it possible to index the site content better and to monitor changes on various webpages which will later be shown in the search engine results, thus a sitemap can raise the ranking of a particular Internet site. Considering the fact that the total number of Internet sites keeps growing every day, using a sitemap is needed if you'd like your site to be more popular.
