301 vs 302 redirects: which one to use and when it actually matters
TL;DR: A 301 redirect tells browsers and search engines a page has permanently moved, and search engines respond by transferring the old URL's accumulated ranking signals (backlinks, authority) to the new URL over time. A 302 redirect signals a temporary move, and search engines deliberately do not transfer ranking signals in the same way, continuing to treat the original URL as the canonical one that might return. Using 302 for a genuinely permanent change (the overwhelmingly common real-world mistake) means your new URL does not properly inherit the old page's search equity, a mistake with no visible symptom for visitors, since both redirect types work identically from a browsing experience, which is exactly why it goes unnoticed.
Why both look identical to a visitor
This is the core reason the distinction matters so much despite being so easy to overlook: from a visitor's browsing experience, a 301 and a 302 redirect behave identically, the browser is sent to the new URL, the page loads, nothing looks or feels different regardless of which type is actually in use. The difference is invisible in the browser itself and only matters to how search engine crawlers interpret and respond to the redirect, which is precisely why using the wrong type produces no immediate, obvious symptom, the site continues working fine for every human visitor, while quietly affecting SEO outcomes that only become apparent weeks or months later through a ranking or traffic change that seems, on the surface, unrelated to a redirect configuration decision made much earlier.
What 301 actually signals and does
A 301 status code explicitly communicates "moved permanently," a deliberate, confident signal that the old URL should no longer be considered the canonical location for this content and that search engines should transfer their understanding of that URL's value, its accumulated backlinks, its established rankings for relevant queries, its general authority, to the new URL over time. This transfer is not instantaneous, and it is not always a perfect, complete 1:1 transfer of every ranking signal, but it is the mechanism specifically designed and intended to preserve the large majority of a page's earned search value through a permanent URL change, when correctly implemented.
What 302 actually signals and does
A 302 status code communicates "moved temporarily," explicitly signaling that the redirect is not expected to be permanent and that the original URL should continue to be treated as the canonical, primary location for the content, since it is expected to return to serving that content directly at some point. Search engines respond accordingly by generally not transferring ranking signals to the destination URL in the same way a 301 triggers, and by continuing to keep the original URL indexed and considered canonical rather than replacing it with the redirect destination.
The most common real-world mistake
By a wide margin, the most common practical error is using a 302 redirect for a change that is actually permanent, commonly because 302 is the default redirect type in many website builders, page builder plugins, and even some hosting control panel redirect tools, meaning a well-intentioned site owner setting up "a redirect" through a convenient interface often ends up with a 302 without realizing a more deliberate choice was even available or that it mattered.
This specific mistake means a genuinely permanent URL change, retiring an old page in favor of a new one, a domain migration, a URL structure change, fails to properly transfer the old URL's accumulated search authority to the new destination, effectively leaving earned ranking value stranded at a URL that is no longer actually being used, a quiet, gradual loss rather than an obvious, immediate error.
When 302 is genuinely the correct choice
302 is not simply "the wrong one to always avoid"; it is the correct, deliberate choice for genuinely temporary situations. A/B testing a new page design or layout, where you want traffic redirected to a variant temporarily while the original remains the canonical, permanent version search engines should continue to associate with the URL. Site maintenance, where a temporary redirect to a maintenance or holding page is expected to be reverted once work is complete. Seasonal or promotional content, where a redirect to a special campaign page is genuinely intended to be temporary and revert to the original content afterward. Geographic or device-based temporary routing, where a redirect reflects a temporary condition rather than a permanent restructuring of your URL architecture.
In each of these cases, using a 301 instead would be the mistake, since it would prematurely signal a permanent change and could cause search engines to deprioritize or replace the original URL in their index even though you intend for it to remain the canonical version once the temporary situation resolves.
A decision table
| Situation | Correct redirect type |
|---|---|
| Page permanently moved to a new URL | 301 |
| Domain migration (entire site moved) | 301 |
| URL structure change (permalink format updated) | 301 |
| Old content retired in favor of new, replacement content | 301 |
| A/B testing a page variant | 302 |
| Temporary maintenance page | 302 |
| Seasonal/promotional page expected to revert | 302 |
| Geographic/device-based temporary routing | 302 |
How to check which type your redirects are actually using
Rather than assuming, check directly: browser developer tools' Network tab shows the actual status code of any redirect when you load the old URL, or a dedicated redirect-checking tool traces the full chain and reports each hop's specific status code, which is particularly useful for auditing many redirects at once (after a migration, for example) rather than checking one at a time manually. If you are using a WordPress redirect plugin, check its specific configuration for each rule, since many plugins do let you choose between 301 and 302 explicitly but may default to one or the other in ways worth confirming rather than assuming.
FAQs
Does it matter which type I use if the redirect is only in place for a few days?
Generally 302 is the more technically correct choice for anything genuinely short-term and intentionally temporary, since using 301 signals permanence that is not actually accurate; however, a few days is unlikely to cause meaningful practical harm either way given how gradually search engines process and act on redirect signals in general.
I used 302 for a permanent change months ago. Can I fix it now?
Yes, simply change the redirect to a proper 301; while some time and potential ranking signal transfer may have been lost during the period it was incorrectly configured as 302, correcting it going forward allows search engines to begin properly recognizing and responding to the permanent nature of the change from that point onward.
Are there other redirect types besides 301 and 302 worth knowing about?
Yes, 307 (temporary redirect, a more strictly defined technical successor to 302 in certain contexts) and 308 (permanent redirect, technically stricter about preserving the original request method) exist and are used in some specific technical contexts, though 301 and 302 remain by far the most commonly used and relevant for typical website redirect scenarios.
Does using the wrong redirect type cause a visible error for visitors?
No, this is precisely why the mistake is so easy to make and so easy to overlook, both redirect types function identically from a visitor's browsing perspective, with no visible difference in behavior, loading, or experience; the difference is exclusively in how search engine crawlers interpret and respond to the signal.
Does WordPress have a default redirect type when I move or rename a page?
WordPress itself does not automatically create redirects when you rename a page's URL slug (the old URL simply stops resolving unless you separately set up a redirect); when using a redirect plugin or manually configuring server-level redirects, checking that plugin or configuration method's specific default and available options is necessary, since defaults vary between tools.
Does a 301 redirect chain (redirecting through multiple hops) cause problems?
Yes, redirect chains (URL A redirects to URL B, which itself redirects to URL C) are generally worth avoiding where possible, since each additional hop adds latency and can, in some cases, result in less complete signal transfer compared to a single, direct redirect from the original URL straight to its final destination; auditing for and eliminating chains, redirecting directly to the final destination URL, is a worthwhile periodic cleanup task.
How long does it take for search engines to fully process a 301 and transfer ranking signals?
This varies and is not instantaneous, generally taking weeks and sometimes longer for a complete transfer to be reflected in rankings, depending on crawl frequency for the specific URLs involved and the overall authority and crawl priority of your site; patience combined with confirming the redirect is correctly and consistently in place (not intermittently working) is the appropriate approach rather than expecting an immediate shift.
Conclusion
301 and 302 redirects behave identically for visitors but signal fundamentally different intentions to search engines, permanent versus temporary, and search engines respond accordingly by transferring ranking signals for 301s while deliberately withholding that transfer for 302s. The most common real-world mistake is defaulting to 302 (often simply because it is a tool's default setting) for changes that are actually permanent, quietly stranding accumulated search value at an abandoned URL with no visible symptom to alert you to the problem.
Audit your existing redirects' actual status codes directly rather than assuming, and correct any permanent changes currently configured as 302 to 301 instead, since this is a straightforward fix once identified but easy to miss without deliberately checking.
