What Is an XML Sitemap Generator?

An XML sitemap generator builds a sitemap.xml file that lists the important URLs of a website, each with optional metadata. The format follows the sitemaps.org protocol, which search engines like Google and Bing read to discover and prioritize your pages. Pair it with the Robots.txt Generator to point crawlers at the sitemap.

How Does This Tool Work?

You provide URLs in two ways. The optional crawl fetches one page through a public proxy and extracts same-site links, because a browser cannot read another domain directly due to CORS. The reliable path is to paste or upload a URL list. The tool then deduplicates and validates the URLs, applies your lastmod, changefreq, and priority settings, and assembles a valid urlset document in real time.

Generating from a URL list happens entirely in your browser. No data is uploaded. The crawl is the only feature that contacts a public proxy.

How to Use the XML Sitemap Generator

• Add your URLs: Enter a site URL and click Crawl, or paste and upload your list of page URLs.
• Set the metadata: Choose change frequency, priority, and last-modified date, or toggle any of them off.
• Use auto priority: Turn on auto priority by depth to score the homepage at 1.0 and deeper pages lower.
• Export: Copy the XML or download sitemap.xml, then copy the robots.txt Sitemap line.
• Publish: Upload the file to your site root and submit it in Google Search Console.

Key Features

• Two input modes: Best-effort crawl plus a paste-or-upload URL list that works for any site.
• Full metadata: lastmod, changefreq, and priority, each individually toggleable.
• Auto priority by depth: Scores pages from their URL path depth automatically.
• Validation and limits: Deduplicates URLs, validates them, and caps the file at the 50,000-URL protocol limit.
• One-click export: Copy or download sitemap.xml and copy the matching robots.txt line.
• Private list mode: The URL-list workflow runs fully in your browser with no uploads.
