XML Sitemap Generator
Build a valid sitemap.xml from a URL list with priority, changefreq, and lastmod — instantly and client-side.
What is an XML Sitemap?
An XML sitemap is a structured list of the URLs on your site — written in the sitemaps.org 0.9 protocol — that tells search engines which pages exist, when they last changed, and how they relate to each other. It is the most reliable way to surface URLs that crawlers might miss through internal linking alone (new pages, deep pages, pages behind faceted navigation), and Google uses the
lastmod field directly to schedule recrawls. The format predates JSON-LD by a decade and remains the canonical machine-readable site index expected at /sitemap.xml by every modern crawler. This generator turns a plain list of URLs into a valid sitemap.xml with optional priority, changefreq, and lastmod values you can paste straight into your repo. Run a full audit on the URLs first with the SEO Checker, or check AI bot access to your robots.txt with the AI Crawler Checker.Add Single URL

What is a sitemap?An XML sitemap is a file that lists all the important pages on your website, helping search engines discover and index your content more effectively.
Why use sitemaps?Sitemaps improve SEO by ensuring search engines can find all your pages, especially new content, internal pages, and pages with few external links.
Change FrequencyIndicates how often a page changes. This is a hint for search engines but does not guarantee crawl frequency. Use realistic values.
Priority ValuesRelative importance of pages on your site (0.0 to 1.0). Use 1.0 for your most important pages and lower values for others.
