A sitemap is a visual or text map of a website - a list of all pages organized in sections as they show up on the Internet site. The sitemap is a single file and its presence can have a substantial effect on the popularity of your Internet site, especially when you have more content. It will permit your visitors to browse through the pages and find what they need way quicker, that will raise the chance for them to revisit the Internet site or to show it to colleagues and friends. The sitemap is also essential for search engines to index your site content better, so that certain pages will appear in the results for specific searches, which will most likely not happen without having a sitemap even when you have the required site content. This is especially valid if you modify some pages since the sitemap informs the search engines that they need to crawl this website again to index the latest content. Having a sitemap these days is essential rather than an optional attribute for any thriving site.
