301 vs 302 Redirects: Which One Should Your Short Links Use?

Every short link is a redirect. You click a short address, and the server sends you somewhere else. What most people never ask is which kind of redirect it is — and that one detail decides whether search engines treat the new address as the real page, or keep showing the old one.

The difference between a 301 and a 302 redirect is simple in principle and easy to get wrong in practice. A 301 says the move is permanent. A 302 says it is temporary. Pick the wrong one for a permanent move and you can leave search engines showing the wrong address for months. Pick a permanent redirect for something you plan to undo, and browsers may keep sending people to the old destination long after you changed your mind.

This guide explains both codes in plain language, clears up the most common myth about them, and shows which one fits short links, campaigns, and tests.

What Is a 301 Redirect?

A 301 redirect means Moved Permanently. The resource has a new address, and that change is not expected to be reversed.

When a browser or a search engine requests the old address, the server answers with a 301 status and a Location header pointing to the new address. The visitor is sent onward, usually without noticing anything at all.

For search engines, a 301 is a strong signal about which address is canonical — that is, which address should be shown in search results. Google groups 301 with 308 as permanent redirects: the indexing pipeline treats the redirect target as the canonical address. In practice, that means:

• The new address is the one that gets shown. Search results point to the destination, not the old address.
• Ranking signals consolidate on the destination. Links pointing at the old address help the new address, because the old address is understood to be the same page under a new name.
• Browsers may cache the redirect. Because the move is declared permanent, a browser can remember it and go straight to the new address next time, without asking the old address again.

That last point is a feature and a warning. Caching makes permanent redirects fast, but it also makes them sticky. If you later change your mind about where a 301 should point, some visitors with a cached redirect may keep landing on the old destination until their cache clears. Do not use a 301 for a destination you expect to change soon.

Typical uses for a 301 include:

• A page that moved for good. A renamed article, a merged page, or a site that changed domains.
• Cleaning up duplicate addresses. Several versions of a homepage address all pointing at one preferred version.
• A retired page with a real successor. An old product page pointing at its replacement, not at the homepage.

What Is a 302 Redirect?

A 302 redirect means Found, and in practice it means moved temporarily. The resource is available somewhere else for now, but the original address is still the real one and should keep being used in future.

The mechanics look identical to a visitor: the server answers with a 302 status and a Location header, and the browser follows it. The difference is entirely in what the codes promise about the future.

For search engines, a 302 is a temporary redirect. Google groups 302 with 303 and 307 as temporary: the indexing pipeline does not treat the redirect target as canonical. In practice, that means:

• The original address stays in search results. Google keeps showing the source address, because you have told it the move is not permanent.
• The destination is treated as a detour, not a replacement. It may still be indexed if other signals point to it, but the redirect alone does not hand it the original address's place.
• Browsers do not treat it as a permanent change. A browser will check the original address again next time, so if you remove the redirect, visitors go back to the original page without a stale cache getting in the way.

That reversibility is the whole point of a 302. It is the safe choice when you are not sure, or when you know the change has an end date.

Typical uses for a 302 include:

• A temporary campaign or promotion. A seasonal page that will come back, or a short-term offer pointing at a campaign page.
• A/B testing. Sending some visitors to a test variant while the original page stays the canonical version.
• Maintenance or a temporary outage. Pointing visitors at an explanation page while the real page is briefly unavailable.
• A page under revision. A placeholder destination while the original content is rebuilt.

Why It Matters for Short Links

A short link adds one more layer to this. The short address itself is a redirect to a longer destination, and the same permanent-versus-temporary question applies to it.

The question to ask is not technical. It is: will this short link mean the same destination in a year, or is the destination a placeholder?

For most short links, the honest answer is the first one. A link printed on packaging, spoken on a podcast, or saved in an email signature is meant to keep working. The destination may be updated if a page moves, but the link itself is a long-term pointer, not a test. That is why the permanent model fits short links: you want the destination treated as the settled address, and you want the short link to keep its value if the destination page ever moves under a new address.

The reverse mistake is just as real. If you create a short link for a flash sale, a test landing page, or a page that will be replaced next week, treating it as permanent overpromises. When the campaign ends, a cached permanent redirect can keep sending people to a dead offer, and search engines may have already started treating the campaign page as the canonical address.

A related trap is redirect chains. If a short link points to a page that itself redirects somewhere else, visitors and search engines have to follow two hops instead of one. Chains slow pages down and dilute the signal about which address is canonical. Whenever a destination moves, update the short link to point directly at the final address instead of stacking another redirect on top of it.

The Link Equity Myth, Corrected

This is the part most guides get wrong, so it is worth stating plainly.

The old story was that a 302 redirect loses link value — that ranking power stops at the original address and never reaches the destination, while a 301 passes it along. Google has said since 2016 that this is not how it works: PageRank passes through redirects of either type. The difference between 301 and 302 is not whether value flows, but where it ends up.

With a 301, the destination becomes the canonical address, so the signals consolidate there. With a 302, the original address stays canonical, so the destination does not inherit the original address's place in search results even though value can flow through the redirect. That is why using a 302 for a permanent move still hurts: not because value is lost, but because search engines keep showing the wrong address.

The practical rule follows from that correction. Do not choose a redirect code to chase link value. Choose it to tell the truth about duration. If the move is permanent, say so with a 301. If it is temporary, say so with a 302. The canonical signal will follow the honest answer.

301 vs 302 at a Glance

• Meaning: A 301 means moved permanently. A 302 means found elsewhere for now.
• Search results: A 301 points search engines at the new address as canonical. A 302 keeps the original address in search results.
• Caching: A 301 may be cached by browsers as a permanent change. A 302 is checked fresh, so removing it takes effect promptly.
• Reversibility: A 301 is hard to undo cleanly once cached. A 302 is designed to be removed.
• Best for permanent moves: 301. Best for temporary detours: 302.
• Close relatives: 308 is the permanent code that preserves the request method exactly, and 307 is the temporary code that does the same. For ordinary page links fetched with a simple request, 301 and 302 are the usual choices; for forms and API endpoints where the method matters, 308 and 307 are the precise tools.

When a 302 Is the Right Call

Temporary redirects get a bad reputation because they are often used by mistake for permanent moves. Used deliberately, they are the correct tool in several common situations for short links and campaigns.

• A/B tests. You want to test a new landing page against the current one without telling search engines the test page has replaced it. A 302 sends visitors to the variant while the original stays canonical. When the test ends, you remove the redirect and nothing needs to be unlearned.
• Temporary campaigns. A short link for a sale, an event, or a seasonal offer that will end. When the campaign closes, the link can go back to the evergreen page, or be retired, without a cached permanent redirect fighting the change.
• Maintenance windows. A page is down for a few hours and you want visitors to see an explanation instead of an error. A 302 keeps the original page in search results while the detour is live.
• A destination you have not settled yet. A new product page is still being built, and the short link currently points at a waitlist or a category page. Until the real page exists and you are sure it is final, temporary is honest.
• Geography or device tests. You are trying a routing rule for a subset of visitors and want to be able to switch it off cleanly. A temporary redirect makes the experiment reversible.

In each case, the test is the same: if someone asked you in three months whether this destination is still correct, would you say yes without hesitating? If not, use a 302.

How to Check What a Short Link Returns

You do not need special software to see which redirect a link uses. A browser's built-in developer tools show it in seconds.

• Open the developer tools. In most browsers, press the key that opens developer tools, or open them from the browser menu, then select the Network tab.
• Turn on recording and clear the list. Make sure network recording is on, then clear any existing entries so the list starts empty.
• Paste the short link into the address bar and load it. Watch the Network tab as the page loads.
• Look at the first entry for the short address. Its status column shows the redirect code, such as 301 or 302, and its headers show the destination address it points to.
• Check for chains. If the destination itself redirects again, you will see a second redirect entry. A clean short link shows one redirect to the final page, not a chain of hops.

This check is worth doing for any short link you print or publish widely. It takes less than a minute, and it catches the two most common errors: a permanent redirect pointing at a temporary campaign page, and a temporary redirect left in place after a move became permanent.

FAQ

Should short links use 301 or 302?

For a short link you intend to keep, the permanent model is the right fit: the link is a long-term pointer and the destination is the settled address. For a short link tied to a test, a temporary campaign, or a placeholder destination, use a temporary redirect so the change can be undone cleanly.

Does a 302 lose SEO value?

No, not in the way older guides claimed. Google has stated that ranking value passes through redirects of either type. What a 302 does not do is hand the destination the original address's canonical place in search results. That distinction, not lost value, is why a 302 is wrong for a permanent move.

What happens if I use a 301 and later change the destination?

Visitors whose browsers cached the permanent redirect may keep going to the old destination until the cache clears, and search engines may take time to update. That is why 301 is reserved for moves you do not expect to reverse. If the destination is uncertain, start with a 302.

What is the difference between 301 and 308, or 302 and 307?

308 is the permanent redirect that preserves the request method exactly, and 307 is the temporary redirect that does the same. For ordinary page links, 301 and 302 behave the same way in practice. The stricter codes matter for forms and API calls, where changing a request method could break the submission.

Can I change a short link's destination after sharing it?

That depends on the link tool, not on the redirect code alone. The safe approach is to decide permanence at the level of the link's purpose: a link you may need to retarget belongs in the temporary mindset until its destination is final, and a link you print widely should point at a stable page. For the Urlzbit side of this, the starter guide below walks through creating and managing links.

Do short links hurt SEO?

A single clean redirect does not hurt SEO. What hurts is a chain of redirects, a redirect to an unrelated page, or a permanent redirect used for a temporary page. Keep redirects to one hop, point at the closest relevant destination, and match the code to how long the move will last.

The Bottom Line

The 301 versus 302 choice is a statement about time, not a trick for ranking. A 301 says this move is for good, and search engines and browsers believe it. A 302 says this is a detour, and everyone checks back later. Most short links are permanent pointers, so the permanent model is their natural home — but a campaign, a test, or a placeholder deserves a temporary redirect, and the honesty of that choice is what keeps your links working when plans change.

Before you publish a short link anywhere permanent, check its redirect code once, the way this guide describes. It is a one-minute check that prevents a months-long mistake.
