A sitemap is a visual or text map of an Internet site - a short list of all webpages grouped in sections as they show up on the site. The sitemap is a single file and its presence can have a substantial influence on the popularity of your Internet site, particularly if you have a lot of content. It will make it possible for your visitors to look through the webpages and find what they need much more quickly, which will raise the possibility for them to come back to the Internet site or to show it to colleagues and friends. The sitemap is also essential for search engines like google to index your site content better, which means that some pages will show up in the results for specific searches, which might not happen without a sitemap even when you have the desired website content. This is especially valid in case you update some pages as the sitemap informs the search engines that they must crawl the website again so as to index the latest content. Having a sitemap today is a necessity rather than an optional attribute for every successful website.
