301 errors are broken or misconfigured redirects – not the redirect itself, which is a normal and often beneficial signal, but the failures around it: redirect chains, loops, or redirects pointing to dead pages. Confusing a working 301 with a 301 error is a common source of unnecessary panic.
A Working 301 vs a 301 Error
A 301 redirect that sends users and search engines from an old URL directly to the correct live page is functioning exactly as intended and passes most ranking signal to the new page. A 301 error is when that chain breaks – the redirect points to another redirect, a 404, or loops back on itself.
Common 301 Error Types
- Redirect chains. Page A redirects to B, which redirects to C. Each hop dilutes signal and slows load time; Google may stop following the chain after a few hops.
- Redirect loops. Page A redirects to B, which redirects back to A, creating an infinite loop that breaks the page entirely.
- Redirects to 404s. The redirect target no longer exists, sending users and crawlers to a dead end.
- Redirects to irrelevant pages. Technically functional, but pointing to unrelated content confuses both users and search engines about relevance.
How to Find and Fix Them
A site crawl tool flags redirect chains, loops, and dead-end redirects directly. Fix chains by pointing the original URL straight to the final destination in one hop, break loops by correcting whichever redirect is circular, and update any redirect pointing to a 404 to the correct live page.
Frequently asked questions
How many redirect hops does Google follow?
Google has stated it will follow multiple hops, but each one adds load time and dilutes signal, so a single direct redirect is always the correct fix rather than relying on chains.
Do 301 redirects hurt SEO?
A single, correctly configured 301 redirect passes the large majority of ranking signal to the new URL and is standard practice – it is redirect errors, not redirects themselves, that cause harm.
How often should I audit my site for redirect errors?
After any major site migration or URL restructuring, and as part of a routine technical audit every few months for an actively changing site.
