An XML sitemap checker validates the sitemap that lists your site's URLs for search engines. It fetches the file, checks the XML formatting, and confirms that every entry points to a live, crawlable page. This free tool flags broken links, blocked URLs, and formatting errors, so you can be sure your sitemap gives Google and Bing an accurate map of the pages you want discovered and indexed.
What the XML sitemap checker validates
The checker retrieves your sitemap and validates it against the XML sitemap protocol. It confirms the file is well formed, uses the correct namespace, and stays within the limits of 50,000 URLs and 50 megabytes per file. It reads each entry, checking that URLs are absolute, use a consistent domain, and return a healthy status rather than a redirect or error. It flags pages that are blocked by robots.txt or carry a noindex tag, since listing them sends mixed signals. For a sitemap index, it follows each child sitemap and checks those too. The result is a clear report of valid URLs alongside any broken, blocked, or malformed entries that need attention.
How to fix sitemap errors
Work through the flagged entries by type. Remove or update URLs that return errors or redirects, so your sitemap lists only final, live pages that respond with a healthy status. Take out any URL blocked by robots.txt or marked noindex, since a sitemap should contain only pages you want indexed. Correct formatting problems such as invalid characters, relative paths, or a missing namespace that stop the file from parsing. If the file is oversized, split it into several sitemaps and reference them from a sitemap index. Once the file is clean, resubmit it in Google Search Console and Bing Webmaster Tools, then monitor the coverage report to confirm the listed pages get crawled.
Why a valid sitemap aids indexing
An XML sitemap is how you tell search engines which pages exist and deserve attention, especially on large sites or ones with pages that are not well linked. A valid, accurate sitemap speeds discovery of new content and helps crawlers spend their budget on the URLs that matter. When the file is broken or full of dead, redirected, or blocked links, it wastes that budget and can slow indexing of your good pages. A clean sitemap also gives clearer signals in Search Console, making coverage issues easier to diagnose. Checking it regularly, and after any migration, keeps the map you hand search engines trustworthy so your important pages get found and indexed.
