Sitemap.xml Generator

What this tool does

This sitemap generator turns a plain list of page URLs into a valid XML sitemap that conforms to the sitemaps.org 0.9 protocol — the format Google, Bing, and other search engines expect. You paste your URLs one per line, choose global defaults for change frequency, priority, and last-modified date, and the tool produces a properly structured <urlset> document with one <url> block per page. You can copy the result or download it as sitemap.xml, ready to upload to your site.

The generator validates every line as you type. Blank lines are skipped, exact duplicates are removed, and any line that is not a valid http or https URL is flagged inline with its line number and a running count, so you can fix typos before publishing. All user-supplied text is XML-escaped, meaning characters such as &, <, and > in a URL become &, <, and > — a quiet but important step, because an unescaped ampersand produces a sitemap that search engines reject as malformed.

Why it matters for SEO

A sitemap is a discovery aid. Search engines find most pages by following links, but pages that are buried deep in the site structure, newly published, or weakly linked can take a long time to be found that way. A sitemap hands the crawler a complete inventory of the URLs you consider worth indexing, which shortens the gap between publishing a page and having it appear in search results. For large sites, content-heavy blogs, e-commerce catalogs, and sites with thin internal linking, this can make a measurable difference to coverage.

The single most valuable element in each entry is lastmod. When it is accurate, crawlers can prioritize re-fetching pages that have genuinely changed and skip those that have not, using your crawl budget efficiently. The changefreq and priority tags are weaker signals — Google has said it mostly disregards them — so treat them as optional metadata rather than ranking levers. What a sitemap does not do is guarantee indexing: each URL is still evaluated on quality and relevance. A sitemap gets pages seen, not ranked.

How to use it

1. Paste your page URLs into the box, one per line. Use absolute URLs that begin with http:// or https://.
2. Review the validation panel — any invalid line is listed with its number so you can correct it. Blank lines and duplicates are handled automatically.
3. Choose a default change frequency and priority, or leave either unset to omit that tag.
4. Optionally set a last-modified date; if set, it is applied to every URL.
5. Copy the generated XML or download sitemap.xml.
6. Upload the file to your site root, submit its URL in Google Search Console, and add a Sitemap: line for it in your robots.txt.

SEO best practices

List only canonical, indexable URLs — the exact versions you want in search results. Exclude pages that are blocked by robots.txt, carry a noindex tag, redirect elsewhere, or return errors; including them sends mixed signals and wastes crawl effort. Keep lastmod honest, updating it only when page content actually changes, because crawlers learn to distrust a sitemap whose dates move without reason. Stay within the 50,000-URL and 50 MB limits per file, and for larger sites use a sitemap index. Regenerate and resubmit the sitemap whenever you publish or remove a batch of pages.

Common mistakes to avoid

A frequent error is including non-canonical or duplicate URLs — trailing-slash variants, parameterized URLs, or http and https versions of the same page — which dilutes the signal you are trying to send. Listing redirecting or 404 URLs is equally counterproductive. Another classic mistake is an unescaped ampersand in a URL, which makes the XML invalid; this tool escapes those for you, but hand-edited sitemaps often break here. Do not pad the file with every URL on the site regardless of value, and do not assume a sitemap will rescue pages that are otherwise un-indexable.

Privacy & your data

This sitemap generator runs entirely in your browser. The URLs you paste and the default settings you select are processed locally by JavaScript — they are never uploaded to a server, never stored between visits, and never logged or tracked. The generated XML exists only in the page until you copy or download it, and it disappears the moment you close the tab. Because nothing leaves your device, the tool is safe to use for staging environments, unreleased sections, or any site map you would rather not share publicly.
