Full XML sitemap validation including structure, URL count, lastmod, duplicates, and sitemap index support.
This check downloads and fully validates your XML sitemap file. It checks the XML structure for errors, counts the total number of URLs (Google allows a maximum of 50,000 per sitemap), verifies the file size stays under the 50MB limit, looks for duplicate URLs, checks if 'lastmod' (last modified) dates are present and valid, and properly handles sitemap index files that link to multiple sitemaps.
Your XML sitemap is like a roadmap you hand directly to search engines, telling them exactly which pages exist on your site and when they were last updated. If this roadmap has errors, missing pages, or wrong dates, search engines may not discover all your content or may waste time re-crawling pages that haven't changed.
Sitemap errors directly affect how well search engines can discover and index your pages. A broken sitemap can mean new content takes much longer to appear in search results, or some pages may never be found at all. This is especially critical for large websites with hundreds or thousands of pages.
