What is HEADMasterSEO?

HEADMasterSEO is a bulk URL checker tool that checks status code, redirect details, response time, response headers and HTTP header fields (X-Robots-Tag, Link, Vary). It let's you analyze, filter and sort the results in real time or export them to CSV. The tool is fast, easy to use and free for checking lists of up to 500 URLs.

Blazing Fast URL Checker

The tool can use HEAD requests to fetch only the server response headers without the response body for faster speed and lower bandwidth consumption. With up to 200 simultaneous URL requests, HEADMasterSEO can extract maximum speed from fast servers.

Check Huge Lists of URLs

HEADMasterSEO is a small and light app that is optimized to run fast and use as little memory as possible. The tool can reliably check 2 to 6 million URLs at a time on modest computers with 4GB to 8GB RAM and up to 30 million URLs on machines with 32GB.

Bulk Check Redirects

Trace the complete redirect path and track details about every URL in a redirection sequence. Filter URLs by redirect type - 301 redirects / 302 redirects / 3XX HTTP status codes, redirect chains and redirect loops. HEADMasterSEO can import and check huge URL lists (millions of links) without choking. It is the best redirect checker for testing large batches of link redirections.

Bulk Test Redirects for Correctness with URL Mapping Rules

HEADMasterSEO can take a list of URLs and a list of URL redirection rules and check if every link redirects to the proper destination using a single SEO friendly 301 redirect. Save hours of your time by writing your URL mapping rules once and then run the redirect tester as many times as needed on your list.
