Sitemap Pro Analyzer

About

Sitemap Pro is a powerful, free XML sitemap analyzer built for SEO professionals, developers, and site owners. Analyze any website's sitemaps with one click — no copy-pasting URLs, no command-line tools, no subscriptions.
 
🔍 ANALYZE
• Auto-detects sitemaps from the current tab via robots.txt and common paths
• Recursively parses sitemap indexes and all child sitemaps
• Validates XML syntax, URL limits (50K), file size (50MB), and structure
• Checks priority values, changefreq, lastmod format, and duplicate URLs
• Detects hreflang annotations and validates language codes
• Identifies sitemap redirects (301/302)
• Results cached locally for fast re-access
 
✅ CHECK URL STATUS
• Send HEAD requests to all URLs or a random sample of 50
• Batch processing with cancellation support
• Reports 200s, 3xx redirects, 4xx/5xx errors, and unreachable URLs
 
🗺️ VISUAL SITEMAP MAP
• Full-page interactive visualization — open in a dedicated tab
• Two view styles: health-aware hierarchy (View 1) or classic tree (View 2)
• Cards show URL counts, health status, and issue indicators
• Smooth bezier connector lines colored by health status
• Click any folder to drill down into a detailed grid view
• Search, zoom, pan, and breadcrumb navigation
• In-popup quick view with tree and sunburst charts
