About this tool

A sitemap lists the pages you want search engines to know about. It does not guarantee indexing — it makes discovery reliable, which matters most for large sites, new sites and pages that are not well linked internally.

Two fields are widely misused. Google ignores <code>priority</code> and <code>changefreq</code> entirely, so setting everything to 1.0 and 'daily' achieves nothing. What matters is that the URLs are canonical, indexable and genuinely yours, and that <code>lastmod</code> is honest.

Duplicates are removed and invalid lines are reported rather than silently dropped, because a sitemap that quietly loses URLs is worse than one that complains.

Common uses

  • Creating a sitemap for a small site by hand.
  • Turning a crawl export into a submittable sitemap.
  • Listing a set of new pages for faster discovery.

Frequently asked questions

Do priority and changefreq help?
Not with Google, which ignores both. Other crawlers may read them. Accurate URLs and lastmod are what count.
How many URLs can one sitemap hold?
50,000 URLs or 50 MB uncompressed. Beyond that, split it and use a sitemap index.
Does a sitemap guarantee indexing?
No. It aids discovery. Whether a page is indexed depends on its quality and the site's overall standing.
