Beyond "does the sitemap validate" — how to audit orphan URLs, lastmod accuracy, and segmentation at scale, and why AI crawlers make sitemap hygiene matter more than it used to.
An orphan page is a live page with zero internal links pointing to it — invisible to crawl-based discovery and doubly invisible to the low-timeout AI crawlers that never render JavaScript or follow deep site trees.

Google has said plainly that it either trusts your sitemap's lastmod dates or it doesn't — there's no partial credit. Here's what the tag actually does, what the record shows about faking it, and how it fits into AI-search freshness signals.
