HTML and XML. HTML sitemaps are designed to be human-readable, while XML sitemaps are designed for machines. Both types of sitemaps can be used by search engines, but XML sitemaps tend to be more effective. Most websites will benefit from having both an HTML and XML sitemap.
Creating a sitemap for your website is relatively simple, and many online tools can help you create one quickly and easily. If you have a small website, you may be able to create your sitemap by hand. However, for larger websites, it is usually best to use an automated tool. Once you have created your sitemap, you will need to submit it to the major search engines. This can usually be done through your website’s control panel or via Google Search Console.
