XML sitemaps are a type of file used to tell search engines about the pages of a website. They are a way to communicate to search engines which pages are important to the website and how they should be indexed. XML sitemaps provide valuable information including the page’s importance relative to other pages on the site, when the page was last updated, and how often the page is likely to change. XML sitemaps are also a great way to notify search engines when new content is added to a website.
When a website is first indexed, search engines will use the sitemap to determine which pages are important and which ones to add to their index. They will also use the sitemap to determine how often to crawl the website, as well as any changes that have been made to the website.
XML sitemaps are a great way for websites to ensure that their content is being properly indexed by search engines. They provide a way for websites to communicate with search engines in a language that they understand and make it easier for search engines to identify and index the important content on a website.
