A sitemap.xml file provides search engines with a list of all the pages on your website that you want to be indexed/crawled.
It helps Google, Bing, and other search engines find all of your content more efficiently and ensures that nothing is missed. It can also provide dates for when each page was last modified, and its priority among the other pages on the website.
It’s important to keep your sitemap.xml file up to date whenever you add new content or remove content from your website.
The good news: there are ways to do this automatically if you use WordPress!
