What this sitemap validator checks

Enter your domain and this free sitemap validator (also a sitemap checker) finds your sitemap — trying /sitemap.xml, sitemap_index.xml and your robots.txt reference — then validates the XML, detects sitemap-index files, and counts the URLs it lists. You get a quick, no-signup confirmation that your XML sitemap is present, well-formed and discoverable.

Why your sitemap matters for AI visibility

A sitemap is how crawlers — search and AI alike — discover every page worth indexing, instead of only the ones they reach through links. If key product or content pages are missing from your sitemap, AI engines are less likely to find them, and a page an engine never sees is a page it can never recommend or cite.

Sitemap best practices

Keep your sitemap at yourdomain.com/sitemap.xml, reference it in robots.txt with a Sitemap: line, list only canonical URLs that return 200, and split very large sites into a sitemap index. After validating, confirm AI crawlers can actually reach those pages with our robots.txt checker.

Frequently asked questions

Why does a sitemap matter for AI visibility?+

A sitemap lists every URL worth indexing, helping AI crawlers discover your full catalog — not just the pages they stumble onto. Missing pages can’t be recommended.

Where should my sitemap live?+

Usually at yourbrand.com/sitemap.xml (or a sitemap_index.xml that points to child sitemaps). Reference it in your robots.txt too.

What is a sitemap index?+

A sitemap index is a sitemap of sitemaps — used by larger sites to group thousands of URLs into multiple files. This tool detects it and samples the first child for a URL count.
