Understanding XML Sitemaps
An XML sitemap is a file that lists all the important pages of a website in XML format. It helps search engines discover and index website pages more efficiently. The sitemap follows a specific XML schema defined by sitemaps.org and includes URL entries with optional metadata like lastmod (last modification date), changefreq (change frequency), and priority (page priority relative to other pages).
XML Sitemap Structure
A valid XML sitemap must follow the sitemap protocol structure: it must start with an XML declaration, contain a urlset root element with the proper namespace, and include url elements with loc (location/URL) as a required child element. Optional elements include lastmod, changefreq, and priority. The validator checks all these requirements and validates URL formats, date formats, and XML structure.
Common Sitemap Errors
Common errors in XML sitemaps include invalid XML syntax, missing required elements, incorrect URL formats, invalid date formats, missing namespace declarations, and non-compliance with sitemap protocol standards. Our validator detects all these issues and provides clear error messages to help you fix problems in your sitemap.
Security and Privacy

Your sitemap content never leaves your device, is never sent to any server, and is never stored or logged anywhere.
