What does Sitemap diff and stale URL auditor do?
It helps you inspect or process this value and get a readable result quickly.
Is my input saved?
Local tools run in the browser when possible. Server-side checks only use the input needed to complete the lookup.
Why should stale URLs be removed from sitemaps?
Stale, redirected, noindex, or 404 URLs waste crawl attention and can reduce trust in the sitemap as a clean discovery source.
Does an old lastmod always mean the URL should be removed?
No. Evergreen pages can stay. But if content has moved, canonical points elsewhere, or status is unhealthy, update, merge, or remove the URL.
