Sitemap XML Generator

Static sites, hand-written HTML landing pages, projects on GitHub Pages: none of them generate a sitemap on their own, and Search Console asks for one. Instead of writing XML by hand and botching an escape, paste your URL list here, one per line, pick changefreq, priority and whether to include lastmod, and copy the assembled sitemap.xml. Escaping of characters like the ampersand, a classic way to invalidate a handmade sitemap, comes out correct.

Two fields in this format matter less than they look: Google has publicly stated that it ignores changefreq and priority. What it does consider is lastmod, and only when the date is trustworthy. Watch out here: the tool fills lastmod for every URL with today's date. If the content did not actually change today, that becomes false information for the crawler; in that case untick the option or edit the dates in the XML before publishing the file.

Save the output as sitemap.xml at the site root, add a Sitemap line with the full URL to your robots.txt, and submit it in Search Console. The protocol caps each file at 50,000 URLs and 50 MB uncompressed; beyond that, split into multiple files and point to them from a sitemapindex. If you publish often, generating the sitemap at build time beats pasting URLs here after every post. Everything runs in the browser; nothing is uploaded anywhere.
