301, 302, 307 and 308 redirects
Redirect checker
Paste up to 20 URLs and see every hop with its status code. We flag chains, loops, temporary redirects and redirects that end in an error.
Following every redirect…
Migrating, redesigning or changing domain?
A badly redirected migration is the fastest way to lose years of traffic. Leave your details and we will tell you how we approach it: redirect map, staging tests and daily monitoring after the switch.
Got it. We will write back within one business day.

Audit before a migration or redesign
Before you change domain, platform or design we review the whole site and build the URL-by-URL redirect map, so every old page reaches its match in one hop.

Technical SEO: clean up redirects
Chains, loops and 302s that pile up over the years cost crawl budget and authority. We sort them, point them to the final destination and keep them from coming back.

What the checker flags
-
Redirect chains
A → B → C. Every extra hop slows the page down and Google may stop following after a few. Point A straight at C.
How to avoid redirect chains → -
Temporary redirects (302, 307)
They tell Google the move is not permanent, so the old URL can stay indexed. For a page that has moved for good, use a 301 or a 308.
What a 302 redirect is → -
Redirect loops
A → B → A. The browser gives up and nobody, Google included, ever reaches the page.
How to fix a redirect loop → -
Redirects to errors
The final URL answers 404 or 5xx. You lose the traffic and the links the old address had earned.
What a 404 error is → -
HTTP and www variants
http:// or the version without www should reach the canonical URL in a single hop, not two or three.
What a 301 redirect is →
Redirects are where most migrations lose their traffic. See how we handle them in our SEO migration case studies, and what Google does with canonical tags when two URLs show the same content.
Redirects: frequently asked questions
-
Paste the old URL into the checker above. It follows every hop the server answers and shows the status code of each one (301, 302, 307, 308, 200 or an error) and the final URL.
-
A 301 says the page has moved permanently, so Google passes the signals to the new URL and drops the old one. A 302 says the move is temporary, so the old URL may stay indexed. 308 and 307 are their equivalents that keep the request method.
-
They waste crawl budget, slow the page down and, past a few hops, Google may not follow them to the end. After a migration, update each redirect so it points straight at the final URL.
-
Up to 20 per check, one per line. For a full migration with thousands of URLs, a crawler and a redirect map are the right tools; that is part of our SEO migration work, and our SEO migration checklist covers the rest.
-
No: it follows the redirects the server answers with an HTTP status code, which are the ones that pass signals reliably. If your site redirects with JavaScript, that is worth fixing.
