Citare Tools · Free
Sitemap Health Checker.
Paste your site URL — we discover the sitemap (default location + any Sitemap: directive in your robots.txt), parse it, follow sitemap-index nesting, and report URL count, <lastmod> coverage, and AI-search-readiness flags.
Free. No signup. Cached 24h.
Why <lastmod> coverage matters for AI search
AI crawlers use <lastmod>tags to decide what’s fresh and worth re-fetching. A sitemap with no <lastmod> tags forces crawlers to re-evaluate every URL on every visit — wasting budget and slowing the discovery of recently-changed content.
Sites with strong <lastmod> coverage (90%+) get faster AI-citation refresh cycles, which matters when you publish new content meant to be cited.
