Sitemap Checker

Your sitemap is how crawlers discover pages and how they learn what changed. This checker fetches /sitemap.xml, validates the XML, counts entries, and checks for lastmod freshness signals.

Next: check whether AI crawlers can even reach those URLs with the Robots.txt AI Crawler Checker. And if you publish often: Bing-family engines accept IndexNow pushes, so new URLs land in hours — the mechanics are in the Copilot GEO guide.
