A sitemap is a file that lists all the pages on a website, helping search engines like Google understand its structure. It acts as a roadmap, guiding crawlers to discover and index content more efficiently. Sitemaps can be in XML format for search engines or HTML format for users, making navigation easier. Creating a sitemap is beneficial for both website owners and visitors. For owners, it improves visibility in search results, while for users, it enhances the browsing experience by providing a clear overview of available content. Regularly updating the sitemap ensures that new pages are quickly recognized.
