About

What is an HTTP redirect checker?

An HTTP redirect checker is a diagnostic tool that fetches a URL the way a browser or search-engine crawler would, follows every 3xx redirect it encounters, and reports the full redirect chain, the response headers, and the SSL certificate at every hop. It's the fastest way to understand what really happens when someone clicks a link.

The status codes you'll typically see are 301 Moved Permanently and 302 Found, as well as 307 Temporary Redirect and 308 Permanent Redirect (less common). Each one tells browsers and search engines something slightly different about whether the move is temporary, whether the request method should be preserved, and whether SEO link equity should be passed correctly to the destination URL.

Long or mistakenly chained redirects, mixed-content downgrades from HTTPS to HTTP, redirect loops, and broken final destinations all silently hurt page speed, conversions, and search rankings. A reliable checker like 3xxRedirects surfaces these issues in seconds so you can fix them before crawlers or users notice.

Features

Built for SEOs, developers, and site owners

Every detail a modern technical SEO audit needs, from full redirect chains to SSL certificate inspection and exportable reports, in a single fast tool.

Full redirect chain

See every 301, 302, 307, and 308 hop (HTTP redirects) from the entered URL to the final destination, with status codes, response header, and response time per hop.

Response headers

Expand any hop to inspect the complete response headers, Location, Cache-Control, CSP, Set-Cookie, HSTS, and everything else the server sent to the client.

SSL certificate details

For HTTPS hops, view the SSL status, issuer (e.g. Let's Encrypt), country, validity dates, days left, key algorithm, and SHA-256 fingerprint hash of the served TLS certificate.

Redirect type detection

Automatically flag HTTP to HTTPS, WWW to Non-WWW, cross-origin, and external redirects, so you can spot wasted hops and protocol downgrades (and fix them!).

CSV, XLS & JSON export

With a single click you can export the entire redirect chain to CSV, XLS (HTML table), or JSON for sharing in audits, tickets, or further analysis in Google Sheets and Excel.

Performance timing

Each hop shows its individual response time in ms so you can identify slow redirects that delay Time to First Byte (TTFB) and potentially hurt Core Web Vitals scoring.

How it works

Three steps to a complete redirect audit

No signup, no install, no command line. Paste a URL and get a full forensic breakdown in just a few seconds.

Paste a URL

Drop any URL (with or without http://) into the input at the top of the page and click Check Redirects. The tool will fetch and analyze the URL.

Inspect the chain

Review every hop's status code, protocol, SSL state, and timing in the results table. Click Details to view the full response headers.

Export or share

Download the full redirect chain as CSV, XLS (HTML tables), or JSON, or copy it to your clipboard to paste straight into a report or ticket.

Reference

HTTP redirect status codes explained

A quick reference to every 3xx redirect status code, what it means, and when search engines pass PageRank through it.

Code	Name	Description
200	OK	The final destination of a successful redirect chain. The page returned content normally.
301	Moved Permanently	Permanent move. Browsers cache the target and search engines pass full link equity. The standard for site migrations.
302	Found	Temporary redirect. The original URL stays in indexes. Useful for A/B tests or geo routing. Method may change to GET.
303	See Other	Instructs the client to fetch the target with GET. Common after a successful POST to prevent re-submission.
304	Not Modified	Not a true redirect. Cached resource still valid based on If-Modified-Since or ETag. Saves bandwidth.
307	Temporary Redirect	Same intent as 302, but the original HTTP method (POST, PUT) must be preserved.
308	Permanent Redirect	Same intent as 301, but the original method must be preserved. The modern, method-safe permanent move.
401	Unauthorized	Authentication is required and has failed or not been provided. The client should retry with valid credentials.
403	Forbidden	The server understood the request but refuses to fulfill it. Often due to IP blocking, bot protection, or missing credentials.
404	Not Found	A broken final destination. Common sign of a missed redirect in a migration that should be fixed with a 301.
410	Gone	Like 404 but explicit. The resource was intentionally removed. Tells search engines to deindex faster.
429	Too Many Requests	The client has sent too many requests in a given period. Servers may include a Retry-After header indicating when to retry.
500	Server Error	The server failed to process the request. Frequent on misconfigured redirect rules or expired SSL.
502	Bad Gateway	A proxy or load balancer received an invalid response from an upstream server. Often transient or caused by a backend crash.
503	Service Unavailable	The server is overloaded or down for maintenance. Should include a Retry-After header indicating when to try again.
504	Gateway Timeout	A proxy or gateway timed out waiting for an upstream response. Often caused by slow databases or downstream services.

Frequently asked questions

Common questions about HTTP redirects, status codes, and how this tool works. Find answers to common questions about this tool.

A 301 tells browsers and search engines that a URL has moved permanently. It's cached aggressively and passes nearly all SEO link equity to the new location. A 302 is a temporary redirect, the original URL should remain in search indexes, and caches treat it as short-lived. Use 301 for site migrations and 302 for short-term routing like A/B tests or seasonal landing pages.

Yes. Every extra hop adds latency, delays Time to First Byte, and gives crawlers another opportunity to give up. Google follows up to about 10 redirects per crawl, but recommends keeping chains to one hop whenever possible. Two or more 301s in a row should be flattened so the original URL points directly to the final destination (fewer redirects are better).

A protocol downgrade from HTTPS to HTTP is almost always a misconfiguration, either in your web server's redirect rules or in a CDN. It triggers mixed-content warnings in browsers and a security ranking penalty in search. Fix it by ensuring all redirects target the https:// version of the URL, and add a strong HSTS header to prevent future downgrades.

Yes. 3xxRedirects is a free online tool with no signup or installation required, it works from your browser. You can check any URL's redirect chain, inspect response headers and SSL certificates, and export results to CSV, XLS, or JSON without any account (just don't abuse it).

For every HTTPS hop, the checker fetches the TLS certificate served by that host and verifies that it is unexpired, name-matched, and signed by a trusted certificate authority. If all three pass, you'll see Valid. Click the Details button on any hop to view SSL issuer, validity dates, etc.

The checker makes an unauthenticated request, just like a search-engine crawler or a logged-out visitor. URLs that require cookies, sessions, or basic auth will return whatever the server sends to anonymous clients, typically a redirect to a login page or a 401/403 response.
