HEADMasterSEO is a bulk url checker tool that lets you quickly audit the response headers of large lists of URLs. Check HTTP status codes, follow redirects and run automated redirection tests. Export results to CSV.

Check URL Status Codes

HEADMasterSEO lets you easily find broken links (404 status code) in your XML sitemaps. Find dead links (status code - 404 Not Found, 410 Gone), redirects (301, 302, 3XX), server errors (5XX status codes) and slow pages.

Check Redirects for Loops and Chains

Find redirect loops and chains. Filter results by redirect type (301 redirects, 302 redirects). Export redirects into a report for further analysis.

Check XML Sitemaps for Errors

Import and check single or multiple XML sitemaps for technical SEO errors (non 200 status codes).

Run Automated Redirect Tests

Are your redirects pointing to the correct destination page? Are you using the correct 301 redirection code without redirect chains? HEADMasterSEO's built-in redirect tester lets you test your redirects using URL mapping rules.

Audit HTTP Response Headers

Check your HTTP response headers for X-Robots-Tag "noindex" directives. Inspect the Vary response header fields. Test URLs for HSTS headers and secure cookies.

Tighten Your Response Headers Technical SEO Setup

HEADMasterSEO is the best tool for auditing server response headers data for technical issues related to status codes and http header fields.

Check Huge Lists of URLs

The url checker can handle huge lists of URLs (about 6 million URLs per 4GB of memory). It runs on Windows and Mac OS X. A special low memory mode can check unlimited amounts of URLs.
