Why it matters
A sitemap full of dead URLs is treated as a low-quality signal: crawlers spend budget on pages that answer 404 or 5xx instead of the live ones. URLs that were not crawled are verified with HEAD probes, up to 100 by default.
How to fix
Remove or fix the URLs reported as unreachable and regenerate the sitemap from real routes. When the sitemap is larger than the probe budget, raise 'sitemap:reachable': ['error', { maxProbes }] (0 = unlimited) or increase crawl.maxPages.
