Paste one URL per line, pick an optional last-modified date, and copy or download a valid sitemap.xml. The preview updates live in your browser, with warnings for duplicates, http:// links, mixed hosts and the 50,000-URL limit.

Built on first-party data from Google and Bing
An XML sitemap is a file, usually at https://yoursite.com/sitemap.xml, that lists the pages you want search engines to find. It follows the sitemaps.org protocol: a <urlset> with one <url> block per page, each holding the full address in <loc> and, optionally, the last-modified date in <lastmod>.
Google and Bing use the sitemap to discover URLs and to see when pages changed. Google says it ignores <changefreq> and <priority>, so a correct <lastmod> matters more than either. List only the final, indexable https address of each page: no redirects, no noindex pages and no URLs blocked in robots.txt.
One sitemap may hold up to 50,000 URLs and 50 MB uncompressed, and only URLs from its own host. Bigger sites split the list into several files and list them in a sitemap index. Read the XML sitemap guide for the full rules, point crawlers at the file with the robots.txt generator, and check the published file with the sitemap validator.
Paste URLs separated by new lines, commas or spaces. Missing https:// is added, hosts are lower-cased, #fragments are dropped and duplicates are listed once.
Flags duplicates, http:// URLs, more than one host, the 50,000-URL and 50 MB limits and non-ASCII URLs, then copy the XML or download sitemap.xml.
The fictional northwind-plumbing.example pastes its home page, a service page typed without https://, a page with a & in the query, and the home page again with a #contact fragment, with a last-modified date of 2026-11-01:
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
<url>
<loc>https://northwind-plumbing.example/</loc>
<lastmod>2026-11-01</lastmod>
</url>
<url>
<loc>https://northwind-plumbing.example/boiler-service/</loc>
<lastmod>2026-11-01</lastmod>
</url>
<url>
<loc>https://northwind-plumbing.example/areas?city=leeds&type=boiler</loc>
<lastmod>2026-11-01</lastmod>
</url>
</urlset>
Example output for a fictional site. It is built by the generator’s own code at build time; replace every URL with your real pages.
The host is lower-cased and gets https://, the & is escaped as &, and the home page with #contact becomes the same URL as the first line, so it is listed once and flagged as a duplicate. Upload the file, then check the live copy with the sitemap validator.
http://www.sitemaps.org/schemas/sitemap/0.9. Without it, search engines do not read the file as a sitemap.&, <, > and quotes escaped so the XML parses.A sitemap should list only final, indexable pages that return 200. Check doubtful URLs with the indexability checker before you add them.
Each host needs its own sitemap. Use the version your canonical tags point to.
If every URL shows today’s date, search engines learn to ignore lastmod. Use the real change date, or leave it out.
A raw & in a query string breaks the XML. The generator escapes it; hand-written files often do not.
Split the list into several sitemaps and list them in a sitemap index file.
Generate one when your CMS does not make it for you, when you launch new pages, or when the sitemap validator finds errors in your current file.
Up to 50,000 URLs and 50 MB uncompressed. If your list is bigger, split it into several sitemap files and list those files in a sitemap index. This generator warns you when you pass either limit.
No. Google says it ignores changefreq and priority, and Bing treats them as hints at most. They are optional here and left out unless you choose a value. An accurate lastmod date is more useful.
No. A sitemap may only list URLs from the host it is served on, so www and non-www, or two domains, need separate sitemaps. The generator warns when your list mixes hosts.
XML reserves the ampersand, apostrophe, double quote and angle brackets, so the generator writes each one as its XML entity inside the loc tag. The file then parses, and search engines read the original URL back.
Upload it to the root of your site, for example https://yoursite.com/sitemap.xml, add a Sitemap: line to robots.txt, and submit it in Google Search Console and Bing Webmaster Tools. Then check it with the sitemap validator.
