Editorial notes

When to consider Sitemap Cohort Auditor

Sitemap Cohort Auditor reads sitemap indexes and compares exact URL sets between releases. It helps identify missing URLs, duplicates and metadata problems before a sitemap change goes unnoticed.

Start here
Run the CLI with Node.js 20 or newer against a local XML or XML.GZ file, or an HTTPS sitemap. Compare it with an earlier snapshot to review added and removed URLs; export JSON or apply a local policy file in CI.
Keep in mind
It checks sitemap declarations without visiting every listed page. Results do not confirm canonical tags, indexing, rankings or traffic.
Free or paid?
Free, open-source software under the MIT license. Runs locally without an account or API key.
