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
- Start with the tested v0.2.2 release and Node.js 20 or newer. Compare two saved XML files and export JSON. That release also documents HTTPS inputs; check the version-specific README before adapting the command.
- 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.

Our test · Sitemap Cohort Auditor v0.2.2
- Input
- before.xml and after.xml from the same fixture, with JSON output and URL-set comparison.
- Observed result
- Read 6 entries representing 5 unique URLs. Found 1 duplicated URL and 1 invalid lastmod; the comparison showed 3 additions and 1 removal.
- Limit
- It does not fetch listed pages, so the declared 404 and noindex URLs need a separate crawl. The test is pinned to v0.2.2; later interfaces may differ.
