An XML sitemap is a file that lists a website’s essential pages, making sure Google can find and crawl them all. It also helps search engines understand your website structure. You want Google to crawl every important page of your website. But sometimes, pages end up without internal links pointing to them, making them hard to find. A sitemap can help speed up content discovery. XML sitemap submission is a process of submitting an XML sitemap to a search engine in order to help that search engine index the contents of your website more effectively. The benefits of doing this can include improved website visibility and traffic.
