An affiliate link, a URL shortener, or an old link pointing to a previous version of your site: any of these can hide a chain of two, three or more redirects before reaching the final destination. Every hop adds loading time and, in some cases, loses SEO authority along the way. Seeing the full chain, hop by hop, is the only real way to know what's actually going on.
What a redirect chain is
When you visit a URL that redirects, the browser doesn't land directly on the destination: it receives an HTTP response with a code (301, 302, 307...) and a new URL to go to. If that new URL also redirects, the process repeats. A redirect chain is the full sequence of hops until reaching the final URL that actually loads content.
The most common redirect codes
- 301 (Moved Permanently): the URL has changed for good. Search engines transfer the old URL's SEO authority to the new one.
- 302 (Found): a temporary redirect. In theory it doesn't transfer SEO authority the same way a 301 does, though in practice modern search engines are more flexible.
- 307/308: stricter versions of 302/301 that guarantee the HTTP method (GET, POST) doesn't change during the redirect.
How to trace a redirect chain
- Enter the starting URL.
- The tool follows each hop, up to 10, showing the HTTP code, destination URL and time for each.
- Review the full chain until reaching the final URL.

Why long chains are a real problem
Every redirect hop involves an additional HTTP request: the browser has to wait for a server's response, receive the new URL, and request again. If there are 4 or 5 hops before reaching the actual content, that time adds up and directly affects metrics like perceived load time. On top of that, every hop is an extra point of failure: if an intermediate server in the chain stops responding, the whole chain breaks.
When to check this on your own site
- After a migration or redesign: to confirm old URLs redirect directly to the new ones, without passing through intermediate versions that shouldn't exist anymore.
- When reviewing internal links: an internal link pointing to a URL that itself redirects is a simplification opportunity (point directly to the final destination).
- When debugging SEO issues: long redirect chains or loops (a URL that ends up redirecting to itself) are red flags that SEO audit tools tend to flag.
Frequently asked questions
How many redirect hops is too many? There's no magic number, but more than 2-3 hops is usually a sign there's something to simplify; ideally, a link should lead directly to its final destination.
Is a 302 worse than a 301 for SEO? For permanent changes, 301 is the right choice; using 302 removes some clarity for search engines about whether the change is permanent, though the real impact varies.
Can there be a redirect loop? Yes, and it's a serious error: the URL never manages to load actual content. This tool detects it by seeing the chain doesn't end at a final destination within the hop limit.
Does it work with URL shorteners? Yes, it's a common use case: seeing where a shortened link actually leads before clicking on it.
