Simply put, an XML sitemap is a bit of Extensible Markup Language (XML), a standard machine-readable format consumable by search engines and other data-munching programs like feed readers. XML sitemaps convey information about one thing: the URLs that make up a site. Each XML sitemap file follows the same basic form. The XML version and urlset are the same for every XML sitemap file. For each URL listed, a <url> and <loc> tag are required, with optional <lastmod>, <changefreq> and <priority> tags. The URL information, outlined in red above, indicates the information that changes for each URL. The <loc> tag simply contains the absolute URL or locator for a page.<Lastmod> specifies the file’s last modification date. <Changefreq> indicates the frequency with which a file is changed. <Priority> indicates the file’s importance within the site.
