XML Sitemap Generator
An XML sitemap generator turns a list of your page URLs into a sitemap file that search engines can read. Paste URLs, one per line, and this free tool checks them, escapes them correctly and builds sitemap.xml. If you have more than 50,000 URLs, it splits them into several files and adds a sitemap index.

Generated Sitemap Files
What is a XML sitemap generator and when should you use it?
A sitemap lists the URLs you want search engines to know about. The XML format is the most common and can carry a lastmod date for each page. Submitting a sitemap is a hint, not a guarantee that every URL will be crawled or indexed. Add the sitemap line to your file with the Robots.txt Generator, and for multilingual pages, build matching entries with the Hreflang Tag Generator.
How do you use it?
- Paste your page URLs or upload a list.
- Choose your options.
- Press Build sitemap.
- Download each file.
- Upload the files to your site and submit them in Search Console or list them in robots.txt.

Result interpretation & practical applications
When evaluating the output of the XML sitemap generator, review the parsed metrics against your specific site architecture. Outputs are formatted for direct implementation into your HTML source, web server configuration, or Google Search Console audit files.
Always inspect generated values for contextual nuance. Automated tools highlight structural patterns, but manual verification confirms that technical directives align with your overarching SEO strategy.
Technical rules and limitations
- One sitemap can hold up to 50,000 URLs or 50 MB uncompressed; larger sets are split, optionally with a sitemap index.
- The file must be UTF-8, use full absolute URLs and escape special characters.
- Google ignores priority and changefreq, and uses lastmod only when it is consistently accurate.
- A text sitemap lists one URL per line and nothing else.
- Submitting a sitemap is a hint, not a guarantee.
These rules come from Google's guide to building and submitting a sitemap.
Common mistakes and troubleshooting
- Using relative URLs such as /page.
- Listing URLs from another site by accident.
- Setting every lastmod to today's date.
- Expecting priority to change anything in Google.
No tool can promise how a search engine will crawl, index, or rank your pages. This tool generates and validates code against documented technical specifications; you determine where to deploy it, and you should always test changes on staging environments first. Google publishes extensive guidelines in Search Central on evaluating third-party SEO tools and advice.
