Some redirect rules decide the destination based on who's asking, which means Googlebot can quietly follow a different path than the one a browser or this checker sees by default. Trace the full chain in seconds: every status code, every hop, every hidden loop.
A redirect can look completely fine to whoever's testing it and still be silently wrong for Google. Plenty of platforms run redirect or middleware logic that branches on the requesting user agent, mobile detection, geo-routing, A/B test buckets. If that logic ever treats a crawler differently from a person, even by accident, the path Googlebot follows stops matching the path everyone assumes is live.
On top of that, ordinary chains accumulate the way they always have: a migration here, a CMS change there, a URL restructure nobody went back and updated. Each extra hop adds latency, dilutes the link equity flowing from backlinks, and risks Googlebot giving up before reaching the destination at all.
Not all redirect problems have the same fix. Here's how to work through the most common ones, in order of impact on rankings and user experience.
If A goes to B goes to C, point A straight at C. Update .htaccess, the Nginx config, or the CMS setting directly, then re-run this checker to confirm every intermediate hop is gone.
Check whether any redirect or middleware rule branches on user agent, mobile detection, or A/B testing. If Googlebot's requests hit a different rule than a normal browser, the path it actually follows can diverge from what every manual check shows. Test by sending a request with Googlebot's user agent string specifically.
Usually conflicting rules in .htaccess, a CDN config, or two CMS plugins fighting each other. List every rule touching the looping URLs and rewrite until there's one clear direction. Clear server and CDN caches before retesting, since stale rules cause phantom loops that look unfixed.
A 302 keeps the original URL in the index and withholds full equity transfer. Update the server directive to a 301, and if a canonical tag sits on the redirected page, confirm it still points to the right master URL afterward.
An error page at the end of a redirect delivers nothing. Restore the destination, point it somewhere relevant, or remove the redirect entirely if the content's genuinely gone.
A single check is fine for one link. A site migrating, restructuring URLs, or running thousands of affiliate or campaign links needs something closer to continuous oversight, because the failure mode here rarely announces itself.
Chains form quietly: a developer updates a page path, the old URL already had a 301 to a slightly different slug, that slug gets moved again later. Eventually a homepage's most valuable backlink is passing through three hops, and nobody noticed because each individual redirect looked fine on its own. The user-agent-conditional case is worse still, since it can look entirely correct to anyone testing it manually and still be wrong for the one visitor that matters most: Googlebot.
TechySEO monitors redirect topology continuously and flags the moment a direct redirect turns into a chain, before it compounds into something that needs surgical remediation.
Redirect chains form silently as a site evolves, and a rule that treats Googlebot differently from a browser can stay invisible for months without ongoing monitoring.
