SEO REVIEW LAB / SITEMAP GENERATOR
Sitemap Generator
Turn up to 500 explicit same-origin page URLs into a UTF-8 XML sitemap with safe entity escaping and optional shared metadata.
Runs in this browser tabNo account requiredOne to 500 non-empty HTTP or HTTPS URLs from one origin; input up to 100,000 characters. Exact duplicate URLs are removed.
Transparent transformation
The workspace uses visible rules, length counts, URL parsing, and standards-shaped templates rather than hidden ranking scores or unverified AI claims.
Human approval required
A technically valid draft can still be inaccurate for a page, campaign, platform, or policy. Test the result and obtain the appropriate approval before release.
Plain-language guide
How the sitemap is constructed
The browser parses every non-empty line as an HTTP or HTTPS URL, requires one exact origin across the set, preserves first occurrence order, removes exact serialized duplicates, and XML-escapes URL text. It writes the Sitemap protocol namespace plus loc and any selected lastmod, changefreq, and priority elements. It does not evaluate canonical tags, status codes, robots rules, redirects, or page quality.
- 01Start with verified inputs
Use preferred canonical URLs that are public and intended for discovery. Exclude redirects, duplicates, private pages, filtered states, and URLs you do not want represented.
- 02Understand the transformation
Nirmion validates one origin, removes exact duplicates, applies the shared optional metadata, escapes XML entities, and creates a standards-shaped UTF-8 document.
- 03Test the destination
Run an XML and sitemap validator, deploy at a suitable public URL, reference it from robots.txt when appropriate, submit it through relevant webmaster tools, and monitor processing errors.
Useful when
Practical jobs this tool supports
- Prepare a small manually curated sitemap for a focused site.
- Generate a test fixture for a development or migration review.
- Remove exact duplicates from a supplied canonical URL list.
Release check
Include only URLs you prefer to surface
A syntactically valid sitemap can still contain redirects, errors, duplicates, or non-canonical pages. Validate the deployed URLs separately.
- Every URL is canonical, public, and intended for indexing.
- All URLs use the same expected scheme, host, and port.
- The shared last-modified date is truthful for every listed page.
- The deployed XML validates and is submitted or referenced correctly.
Important boundary
The generator does not crawl or scale automatically
This release is intentionally limited to 500 supplied URLs and one shared metadata profile. Larger or frequently changing sites should generate sitemaps from authoritative application data and follow protocol limits, indexes, and search-engine guidance.
Read the Sitemap protocol specificationQuestions before publishing
What a careful user should know
A sitemap is a discovery signal built from authoritative URLs, not a replacement for crawlable navigation or correct canonicalization.
Does the tool discover my site pages?
No. It makes no network request and includes only the URLs you enter.
What counts as a duplicate?
Exact serialized URL duplicates are removed. Semantically similar URLs with different case, parameters, slash form, or host remain distinct for human review.
Does inclusion guarantee indexing?
No. Search engines independently crawl, canonicalize, evaluate, and index URLs. A sitemap communicates preferred URLs but cannot guarantee inclusion.
