About Sitemap Checker – Freshness, Robots.txt & AI Bot Audit

Sitemap Checker is a side-panel SEO tool for auditing any website's sitemap health, content freshness, robots.txt rules, AI-crawler access, and canonical tags in seconds — no server, no login, no data leaving your browser. What it checks: Sitemap health — broken URLs (404/500), missing <lastmod> tags, orphaned/broken sub-sitemaps, duplicate entries Content freshness — a distribution chart of how recently pages were last modified, plus a ranked list of the stalest pages on the site robots.txt consistency — flags sitemap URLs that are actually disallowed by robots.txt (a common and embarrassing technical SEO bug) AI crawler access — see at a glance which pages are blocked from GPTBot, ClaudeBot, Google-Extended, PerplexityBot, and 8 other AI/LLM crawlers Canonical tag audit — finds pages whose canonical tag points somewhere other than themselves, or is missing entirely CSV export — full results exportable for client reporting Handles sitemap index files (nested sitemaps), not just flat sitemap.xml files. Everything runs locally in your browser — the extension never sends your data to any external server. Built for SEO consultants, agencies, and site owners who want a fast technical audit without spinning up a crawler tool.
