An XML sitemap is a file that lists a site's URLs so search engines can discover and crawl them more efficiently — especially useful for large sites, sites with pages that aren't well linked internally, or sites that publish new content often.
This tool takes a plain list of URLs, one per line, and generates a standards-compliant sitemap.xml file following the sitemaps.org protocol that every major search engine supports. Invalid lines are automatically separated out rather than breaking the whole batch, so you can fix just the problem entries.
How it works
Paste your URLs, one per line, into the text box. Optionally choose a default change frequency and priority to apply to every URL. The tool validates each line, builds a sitemap.xml with a <loc>, <lastmod>, and (if set) <changefreq> and <priority> tag for every valid URL, and flags any lines that aren't valid URLs so you can fix them.
- Paste your URLs, one per line.
- Optionally choose a default change frequency and priority.
- Click Generate Sitemap and download the XML file.
Examples
A simple sitemap for a small site
Pasting 15 page URLs generates a ready-to-upload sitemap.xml in seconds, without needing a crawler or a CMS plugin.
Catching a typo in a URL list
A list with one line reading "example.com/page" instead of a full URL with "https://" gets flagged as invalid and excluded, while the other valid URLs still generate correctly.
Who should use it
- Generating a sitemap.xml for a small to mid-size site without a CMS plugin.
- Rebuilding a sitemap after a URL structure change.
- Creating a custom sitemap for a subset of pages you want search engines to prioritize.
Industry applications
- SEO and technical SEO
- Web development and site migrations
- Content publishing and site maintenance
Advantages
- Generates a standards-compliant sitemap.xml in seconds from a plain URL list.
- Automatically separates invalid lines instead of rejecting the whole batch.
- No signup, crawler setup, or CMS plugin required.
Limitations
- Doesn't crawl your site automatically — you supply the URL list yourself.
- Doesn't validate that each URL actually returns a 200 status or is reachable.
- Large sites (50,000+ URLs) need a sitemap index of multiple files, which this single-file generator doesn't build.
Common mistakes to avoid
- Submitting relative paths instead of full URLs with a scheme (http:// or https://).
- Including URLs that redirect, 404, or are blocked by robots.txt, which wastes crawl budget on invalid entries.
- Setting every URL's priority to 1.0, which defeats the purpose of priority as a relative signal between pages.
Best practices
- Only include canonical, indexable URLs that return a 200 status — not redirects, duplicates, or noindexed pages.
- Vary priority meaningfully across your most and least important pages instead of setting one flat value.
- Reference your sitemap's URL in robots.txt so search engines can discover it automatically.
Tips
- Keep sitemaps to only canonical, indexable URLs — a "clean" sitemap is a stronger signal than a comprehensive but noisy one.
- Regenerate and re-upload your sitemap whenever you add, remove, or restructure a meaningful number of pages.
