A sitemap is a visual or text map of a website - a short list of all web pages arranged in sections as they show up on the website. The sitemap is a single file and its presence can have a considerable impact on the popularity of your site, particularly if you have more content. It will make it possible for your site visitors to go through the pages and find what they need quicker, which will raise the chance for them to come back to the website or to show it to colleagues and friends. The sitemap is also required for search engines to index your content better, so that some pages will show up in the results for specific searches, which may not happen without having a sitemap even when you have the required content. This is especially valid when you modify some pages because the sitemap tells the search engines that they have to crawl the internet site again in order to index the latest content. Having a sitemap nowadays is essential rather than an optional feature for any profitable Internet site.
