How It Works
Three simple steps to trace any link

Drop any shortened or suspicious link into the input. We accept raw URLs, short links, and redirect chains.
Trace the Chain
Redirect Sniffer follows HTTP redirects and meta refreshes to map the complete path without executing page scripts.
See the Destination
Review the full redirect chain with status codes, response times, and the final destination URL.

A URL redirect is a technique used to forward one URL to a different URL. When you click a link or type a web address, redirects automatically send you to the final destination, often through multiple intermediate steps.
Redirect Sniffer traces every hop in that chain so you can see exactly where a link leads — before you click it. This is useful for link QA, SEO analysis, debugging, and understanding how shortened URLs work.
SEO Analysis
Spot long redirect chains that add latency and make migrations harder to verify.
Link Safety
Preview the destination and review useful link signals before opening a shortened URL.
Debugging
Find broken redirects, loops, status errors, and slow hops in one clear path.
Campaign QA
Confirm that affiliate, advertising, and tracking links reach the intended landing page.
