301 SEO

Preserves most of the link equity and ranking signals from an old URL when you move content permanently to a new address.

If you have ever redirected a set of unrelated URLs to your homepage because it was easier, you already know that shortcut costs you traffic and relevance.

Key points

  • Redirect each old URL to the closest equivalent page, not the homepage.
  • Avoid redirect chains longer than one hop—update the destination to point directly to the final URL.
  • Update internal links, canonicals, and XML sitemaps to point to the final URL, not the redirect.
  • Test all redirects to confirm they return a 301 status and land on the correct destination.
  • Use a 301 only for permanent changes; for temporary moves, use a 302 redirect instead.

Migrating a blog without losing traffic

When Example.com moved its blog from /blog/ to /articles/, they set up a 301 redirect for each of the 200 old URLs to the specific new URL. Organic traffic recovered within six weeks, and only 5% of the link equity was lost according to internal tracking. The mistake they avoided was redirecting everything to the homepage, which would have confused both users and search engines. This is a textbook 301 redirect seo case: permanent, direct, and tested.

Three situations where a 301 redirect is the right choice

  • Permanent URL change When a page moves to a new domain or path and will never return, a 301 tells search engines to transfer signals to the new address. This is the standard SEO redirect for such moves.
  • HTTPS migration Switching from HTTP to HTTPS requires a 301 from each old URL to its HTTPS equivalent. Without it, both security and ranking signals are lost.
  • Content consolidation Merging two similar pages into one stronger page uses a 301 to send the old URL's authority to the surviving page. Proper redirect SEO ensures the new page benefits fully.

Three common mistakes that waste your redirect's value

  • Homepage dumping Redirecting dozens of unrelated URLs to the homepage instead of the closest relevant page wastes the link equity and confuses users. Domain forwarding seo done poorly does exactly this.
  • Redirect chains A 301 from A to B, then another from B to C, forces crawlers to follow multiple hops, risking timeout and value loss. Always aim for a single direct hop.
  • Neglecting internal links Leaving internal links, canonicals, and sitemaps pointing to the old URL means users and bots still hit the redirect, adding latency. Update them to the final URL.

Common questions

What is a 301 redirect?

A 301 redirect is an HTTP status code that tells browsers and search engines a URL has moved permanently to a new address. It preserves ranking signals.

302 redirect vs 301 – what is the difference?

A 302 is a temporary redirect; a 301 is permanent. Search engines treat a 301 as the final destination, while a 302 keeps the original URL as the intended target.

Does a 301 redirect hurt SEO?

No, a 301 redirect is the standard way to move URLs without a penalty. Outdated myths about a 301 redirect seo penalty are false.
