XML Sitemap Generator
Turn a list of URLs into a valid sitemap.xml, split and indexed if large.
A Clean sitemap.xml From The URLs You Choose
Paste the list of pages you want search engines to index — or paste a page’s HTML and let the tool collect its links — and get a standards-compliant sitemap.xml. Duplicates are removed, fragments and tracking parameters can be stripped, and every URL is XML-escaped, fixing the single most common reason a sitemap fails to parse: a bare ampersand.
URLs on other hosts are left out, because a sitemap may only list its own site. Past the protocol’s limit of 50,000 URLs the list is split into several files with a sitemap index, delivered as a ZIP. Set an accurate lastmod — the one field Google says it uses — and leave changefreq and priority out unless you need them.

Frequently asked questions
Which URLs should be in my sitemap?
Only canonical, indexable pages that return 200: the exact URLs in each page’s canonical tag, on one scheme and host. Leave out redirects, pages blocked from indexing, duplicates and parameter variants.
Does Google use changefreq and priority?
No. Google has said it ignores both and uses lastmod only when it is consistently accurate. Other search engines may read them, which is why they remain optional.
How many URLs can one sitemap hold?
50,000 URLs or 50 MB uncompressed, whichever comes first. Larger sites use several sitemaps listed in a sitemap index file.
Where do I put the sitemap?
Usually at https://yoursite.com/sitemap.xml. Reference it in robots.txt with a Sitemap: line and submit it in Google Search Console and Bing Webmaster Tools.
Why does my sitemap fail with an XML error?
Usually an unescaped & in a URL, or a byte-order mark or whitespace before the XML declaration. This generator escapes every special character and writes the declaration first.
