AI Sitemap Validator
Paste your sitemap.xml and check what crawlers, including AI ones, rely on: valid XML, URL limits, duplicates, HTTPS and fresh lastmod dates.
Why the sitemap matters for AI search
AI search crawlers such as OAI-SearchBot and PerplexityBot discover pages the same way search engines do: through links and through the sitemap declared in robots.txt. Accurate lastmod dates tell them what to re-read first, so new and updated pages reach AI answers sooner. The check runs in your browser against the sitemaps.org protocol.
