XML sitemap testing tool to automatically validate sitemaps
What is the XML sitemap checker for
Analyze and test XML sitemap files and XML sitemap index files and find issues
Identify invalid URLs, duplicate URLs and missing or inaccurate lastmod definitions
Debug complex sitemaps with cross domain hreflang, videos or image definitions
Detect XML sitemaps that are too big, have too many URLs or cause parser errors
How to check sitemap files
Optimize crawling of your website with validated XML sitemaps for all your important URLs
Our XML sitemap validator checks for common errors and highlights optimization potential. Correct sitemap files highly contribute to a better crawling of changed URLs, resulting in a more up to date search index.
Sitemap features for complex websites
Automated XML sitemap discovery
Sitemaps within sitemap index files, that are part of the crawl, are automatically discovered and analyzed by the sitemap crawler tool. Multiple starting points can be in a single crawl.
Cross domain hreflang validation
Validate Hreflang within XML sitemaps and check hreflang groups and all pages for errors, even for large multi domain websites.
Image and video sitemap support
Specialized XML sitemap formats for images and videos are supported and the referenced files are checked for availability.
Check a XML sitemap implementation
Identify XML sitemap parser issues
Discover if a XML sitemap file causes parser issues e.g. due to an incorrect MIME type or content encoding. The XML sitemap tester also finds sitemaps that are too big.
URL related sitemap issues
Find problematic URLs referenced in a XML sitemap that are invalid, empty, not normalized, not properly URL-escaped or duplicates.
Lastmod date and time issues
Detect problems with the <lastmod> specification that conflict with optimized crawling like invalid dates, missing times or a dates in the future.
XML sitemap coverage and reachability
Explore all URLs linked from XML sitemaps and quickly discover if all important URLs are included. Research problems with pages only accessible via XML sitemaps.
