Referrer policy checker
Referrer policy checker reads the Referrer-Policy response header. Review its value before investigating how pages disclose referral information in requests.
Referrer policy checker: what this tool checks
Referrer policy checker inspects the Referrer-Policy header returned for a submitted URL. The result helps developers confirm that a desired header reaches visitors after a server configuration or delivery rule change. It exposes the value for review without attempting to reproduce every outgoing browser request.
How to use it
- Enter the complete page address and submit the check.
- Read the reported header value and whether it was detected.
- Compare it with your intended policy, then test relevant navigation and resource requests in the browser.
Understanding your results
A detected header is marked enabled; an absent value is marked disabled. Those labels describe header presence only. They do not validate policy tokens or account for HTML meta declarations, individual link attributes, browser defaults, or every rule that may affect the eventual referrer information.
Frequently asked questions
Does disabled mean the browser sends everything?
No. An absent header is not a measurement of actual disclosure. Other declarations and browser behavior can still govern what is sent, so inspect real requests when investigating a specific case.
Can this prove that analytics attribution is correct?
No. Analytics also depends on redirects, consent, tracking implementation, and the destination system. This checker identifies one header value rather than validating a complete measurement workflow.
