A sitemap is a visual or text map of a website - a short list of all webpages organized in sections as they show up on the website. The sitemap is a single file and its presence could have a crucial influence on the popularity of your website, particularly when you have more content. It will allow site visitors to browse through the pages and find what they need much quicker, which will raise the possibility for them to revisit the site or to show it to friends and colleagues. The sitemap is also required for search engines like google to index your content better, so that some pages will appear in the results for certain searches, which might not happen without a sitemap even if you have the needed website content. This is especially valid if you update some web pages as the sitemap informs the search engines that they must crawl the website again in order to index the new content. Having a sitemap nowadays is essential rather than an optional feature for every profitable Internet site.
