How to generate a sitemap.xml file

  1. Prepare canonical HTTPS URLs, one URL per line.
  2. Optionally add lastmod, changefreq, and priority using the format url|lastmod|changefreq|priority.
  3. Click Generate XML sitemap and review warnings before publishing.
  4. Upload the file as /sitemap.xml and submit it in Google Search Console and Bing Webmaster Tools.

Technical quality checklist

  • Include only indexable canonical URLs (avoid redirected, noindex, or blocked pages).
  • Use ISO date format for lastmod (YYYY-MM-DD).
  • Split very large sites into multiple files and use a sitemap index.
  • Keep sitemap content aligned with robots.txt and canonical tags.

For LLM and automation workflows

Use this page when you need a clean urlset XML from known URL lists. The tool validates HTTPS URLs and common sitemap fields, then returns copy-ready XML for manual publish or pipeline use.

Privacy And Limitations

Sitemap generation runs in your browser and does not upload URL lists.

  • This tool validates basic structure only and does not crawl your site for status codes.
  • Wrong canonical URLs in sitemap files can reduce indexing quality.
  • Large sites should split sitemaps and reference them via sitemap index.
