In-depth guide

Sitemap generator

Generate valid sitemap.xml content quickly from URL lists and optional metadata fields.

Input format

Each line accepts either only a URL or a CSV tuple: URL,lastmod,changefreq,priority.

Sitemap limits

Each sitemap supports up to 50,000 URLs and 50MB uncompressed. Use sitemap index files for larger sites.

How to build it

Paste one URL per line, optionally adding lastmod, changefreq and priority as comma-separated fields.
Copy the generated XML into a sitemap.xml at your site root.
Reference it from robots.txt and submit the URL in Google Search Console and Bing Webmaster Tools.

Use absolute URLs with the same protocol and host as your live site so crawlers do not treat them as separate pages.

Pitfalls and privacy

Google treats changefreq and priority as hints it largely ignores, and it only trusts lastmod when it is consistently accurate — so do not fake dates. Only list canonical, indexable URLs; including redirects, 404s or noindex pages wastes crawl budget. The XML is assembled locally in your browser and your URL list is never uploaded.

When to use it vs alternatives

Use this tool for quick browser-based work when you need an answer or output immediately. Use a dedicated application or automated workflow when you need bulk processing, approvals, or repeatable production rules.

Frequently asked questions

Can I include lastmod and priority?

Yes. Use CSV format per line: URL,lastmod,changefreq,priority.

Is the XML escaped correctly?

Yes. Special characters are escaped into valid XML entities.

Does this submit sitemaps to search engines?

No. This tool generates sitemap XML only.

Should I set changefreq and priority?

They are optional hints that Google largely ignores. lastmod is more useful, but only if it is accurate.

Which URLs should I include?

Only canonical, indexable URLs that return 200. Avoid redirects, 404s and noindex pages so you do not waste crawl budget.

What are the sitemap size limits?

A single sitemap allows up to 50,000 URLs and 50MB uncompressed. Split larger sites across multiple files and reference them from a sitemap index.
