How many URLs can one sitemap list?

Up to 50,000 URLs, in a file no larger than 50 MB uncompressed. Larger sites split their URLs across several sitemaps and list them in a sitemap index.

Does Google use priority and changefreq?

No, Google ignores both. It uses lastmod when the dates are consistently accurate, so change lastmod only when the page content changes.

Does it check every sitemap in an index?

No, it validates the file you give it, so run it on each child sitemap. It also cannot confirm that Google has read the file; Search Console's Sitemaps report does that.

How much does the XML Sitemap Validator cost?

10 credits per run, shown before the run starts. An AI agent can run the same tool over the REST API or MCP with a workspace API key.
