Sitemap Analyzer
Analyze XML sitemaps for SEO errors. See total URLs, check for broken links, and verify last modified dates. Note: We check a sample of up to 50 URLs for status codes.
Free Sitemap Analyzer
A healthy sitemap is the express lane to Google's index. Our free analyzer parses your XML sitemap, checks every URL's HTTP status, and surfaces the errors killing your indexation rates.
What Our Free Sitemap Analyzer Checks
URL Status Verification
We fire concurrent HEAD requests against a sample of your sitemap URLs and report back real HTTP status codes. Find 404s, 500s, and unwanted 301 redirect chains before Googlebot wastes crawl budget on them.
Sitemap Index Support
Large sites use sitemap index files containing dozens of child sitemaps for products, posts, and images. Our free analyzer recursively unpacks sitemap indexes and presents a unified view of your entire URL architecture.
Metadata Validation
We extract lastmod, changefreq, and priority tags from each URL entry. Missing or outdated lastmod dates cause Googlebot to recrawl on its own schedule rather than when you actually update content.
How the Free Sitemap Analyzer Works
- 1
Paste Your Sitemap URL
Enter the direct URL to your sitemap file (e.g., yourdomain.com/sitemap.xml or /sitemap_index.xml). Our system makes a server-side request to fetch the raw XML.
- 2
XML Parsing & Structure Analysis
We use a standards-compliant XML parser to walk through each URL entry, extracting location, lastmod, changefreq, and priority values into a structured format.
- 3
Concurrent HTTP Health Checks
A sample of entries are simultaneously checked via HTTP HEAD requests to verify actual server availability. We capture the status code and flag anything that isn't a clean 200 OK.
- 4
Visual Summary Report
Results are presented as a full statistics dashboard: total URLs, healthy vs. broken counts, and a sortable table for drilling down into specific issues.
The Hidden Danger: 404 URLs Inside Sitemaps
Sitemaps become stale. A product page you deleted six months ago might still be listed in your sitemap, quietly sending Googlebot on pointless 404 crawls. Over time, repeated errors erode crawler trust in your domain. Our free analyzer exposes these ghost URLs so you can rebuild a clean, authoritative sitemap that search engines treat as a reliable signal.
Sitemap Size Limits and Index Files
Google enforces a hard limit of 50,000 URLs per sitemap file and a maximum uncompressed file size of 50MB. Enterprise ecommerce stores with millions of SKUs routinely exceed these limits. The solution is a sitemap index file that references multiple child sitemaps. Our tool fully supports sitemap indexes and drills into each referenced child file automatically.
The lastmod Tag: Your Content Freshness Signal
The lastmod tag tells Googlebot when you last modified a page. If you update a core landing page but forget to update its lastmod value, Googlebot may delay recrawling it for weeks. Keeping lastmod values accurate and current is one of the highest leverage, lowest effort technical SEO improvements available.
