301 vs 302 Redirects: When to Use Each for SEO

When a URL changes, what should happen to someone who visits the old address? HTTP redirects send users and crawlers to a different destination, but 301 and 302 communicate different intentions. A 301 indicates a permanent move; a 302 indicates a temporary one. The correct choice depends on your actual content and migration plan rather than a simplistic rule about which code “ranks better.”

When is a 301 redirect appropriate?

Consider a permanent redirect after a durable URL rename, an HTTP-to-HTTPS migration, or the consolidation of equivalent content. If /blog/old-guide/ has moved permanently to /blog/new-guide/, the old URL can point to the closely matching new resource. Redirecting unrelated old pages to the home page often fails to satisfy the user’s original intent.

Examples of temporary 302 redirects

A short campaign may direct visitors to a special landing page for a limited period. Temporary maintenance may also call for a short-lived alternate location. In both cases, you expect the original URL to resume normal use. Keeping a truly permanent move behind a 302 for a long time may produce inconsistent signals about the preferred destination.

What is a redirect chain?

A chain might look like /old/ → 301 → /intermediate/ → 302 → /new/. Each hop can add another network request and another opportunity for failure. Update internal links to point directly to the final destination where possible. A migration is also a chance to remove legacy loops and unnecessary redirects.

Worked example: moving a service page

Suppose https://example.com/services/seo/ moves permanently to https://example.com/seo-consulting/. Request the old URL: it should return the expected 301 and a Location header pointing to the new address. Following the redirect should reach a useful, accessible final page. If the destination returns 404 or loops back to the original URL, the migration is incomplete.

Weak implementation: Redirect every old URL to an unrelated home page. Better implementation: Map each old resource to its closest relevant replacement and review cases without a suitable alternative individually.

Migration checklist

1. List old URLs and their intended destinations.
2. Identify permanent versus temporary changes.
3. Test redirect status codes, chains and final page availability.
4. Update internal links, canonical tags and XML sitemaps.
5. Monitor important addresses in Search Console.
6. Check high-value historical external links and bookmarks.

Use Redirect Checker for individual URL chains and the Site Crawler for wider internal-link issues.

Redirects, canonicals and sitemaps should agree

Once a resource moves permanently, keeping the old URL in your sitemap is generally unhelpful. The final destination should have a consistent canonical annotation. Read our canonical guide to understand preferred addresses. If your sitemap still contains redirecting URLs, compare them with the live site and correct the outdated entries.

Frequently asked questions

Does a 301 instantly transfer all SEO value?

There is no guaranteed numeric transfer or immediate timeline. Content equivalence, crawling and other signals matter.

Is a 302 always bad for SEO?

No. A genuinely temporary redirect can be the correct technical choice.

When can I remove old redirects?

There is no universal deadline. Consider real visitor behavior, bookmarks and links that may continue using older addresses.
