#XML sitemaps
An XML sitemap is a file that lists the URLs you want search engines to know about. Articles tagged here explain what belongs in a sitemap and what should stay out. They cover sitemap indexes, lastmod dates, size limits and submission in Search Console. Each guide shows how to find sitemap URLs that redirect, return errors or are set to noindex. You will also learn how popular WordPress plugins generate sitemaps. A clean sitemap is a clear list of the pages that matter.
