Redirect Checker & HTTP Header Tester
Trace every redirect hop, test http/https and www/non-www canonicalization, and grade your security headers.
About this tool
A site should resolve to exactly one version. This tool follows every redirect in order, tests all four versions of your domain (http, https, www, non-www) and lists your response and security headers.
How to use the Redirect & Header Checker
- Enter any URL on your site.
- Review the redirect path and timing.
- Check that all four domain versions end at the same URL.
- Add any missing security headers.
Frequently asked questions
301 or 302?
Use 301 for permanent moves. 302/307 are for temporary changes and may not pass full ranking signals.
What is a redirect chain?
More than one redirect in a row (A→B→C). Each extra hop slows users and crawlers.
