You moved a page, set up a redirect, and called it a day. The thing is, not all redirects work the same way, and picking the wrong one can quietly chip away at your search rankings without you even noticing.
301 and 302 redirects might look like small technical details, but they send very different signals to Google. Get it right and your SEO stays intact. Get it wrong and you could be leaking link equity for months.
Here is everything you need to know to make the right call every time.
What Is a Redirect?
A redirect is an instruction that sends both users and search engines from one URL to another. When a page moves, gets deleted, or needs to point somewhere else, a redirect makes sure nobody lands on a dead end.
There are several types of redirects you should know about:
- 301 Redirect: A permanent redirect. It tells search engines the page has moved for good and passes the majority of link equity to the new URL.
- 302 Redirect: A temporary redirect. It moves traffic to a new URL for now, but signals that the original page will come back.
- 303 Redirect : Used after form submissions to prevent duplicate submissions on page refresh.
- 307 Redirect : The HTTP/1.1 version of a 302. Temporary, and it preserves the request method.
- 308 Redirect : The permanent version of a 307. Similar to a 301 but stricter about the request method.
- Meta Refresh : A page-level redirect that runs in the browser, not the server. Slow, bad for SEO, and best avoided.
For most SEO and web management purposes, the ones that matter most are the 301 and 302 redirects.
Permanent Move? A 301 Redirect Has You Covered
When a page moves to a new URL for good, a 301 redirect is what communicates that change to both users and search engines. The server fires back an HTTP status code of “301” and Google gets the message loud and clear: the old page is done, and the new one is where attention should go.
This matters a lot from an SEO perspective. The link equity, the authority built up over time through backlinks and engagement, gets transferred to a new URL. Your rankings have a fighting chance of staying intact rather than disappearing overnight.
When does a 301 redirect make sense?
- You permanently moved a page to a new URL
- You migrated to a new domain
- You consolidated two similar pages into one
- You switched your site from HTTP to HTTPS
- You deleted a page but have a solid alternative to redirect users to
Google is pretty decisive about 301 redirects. Once it processes the signal, it will gradually stop crawling the old URL and fully index the new destination in its place.
Worth noting: the link equity transfer is not instant. It can take several crawl cycles before Google fully shifts its attention to the new URL, so patience is part of the process.
If a page is moving and it is not coming back, a 301 redirect is the right tool for the job, full stop.
Just Passing Through? That Is What a 302 Redirect Is For
A 302 redirect tells users and search engines that a page has temporarily moved to a new URL. The server returns the HTTP status code “302” and Google reads that as: the original page is still relevant, so keep it indexed.
This is where a lot of people trip up. Because the move is flagged as temporary, Google holds on to the original URL and doesn’t give link equity to the destination page. That is completely fine when used correctly, but it becomes a real problem when someone uses a 302 where a 301 should be.
When does a 302 redirect make sense?
- You are running a limited time promotion on a separate page
- You are A/B testing two versions of a page
- You are doing maintenance and temporarily rerouting traffic
- You want to test a new page design before making it permanent
- You need to redirect users based on their location or device, temporarily
The key word across all of those scenarios is temporary. If the original page is coming back, a 302 redirect is the right move. If it is not coming back, switch to a 301 before Google starts making assumptions.
Search engines are patient, but they are not mind readers. Tell them exactly what is going on with the right status code.
301 and 302 Redirects: What Actually Sets Them Apart?
On the surface, both redirect types do the same thing. They move traffic from one URL to another. But the signal they send to Google is completely different, and that difference has real consequences for your SEO.
How Do They Compare?
Purpose
A 301 redirect signals a permanent move. A 302 redirect signals a temporary one. That single distinction is what drives every other difference between the two.
Link Equity
With a 301 redirect, the majority of link equity from the old URL gets passed to the new one. With a 302, Google holds on to the original page and does not transfer that authority. Use the wrong one and you could be sitting on a page that never builds any real ranking power.
Indexing Behaviour
Google will eventually drop the old URL from its index when it sees a 301 redirect and replace it with the new destination. A 302 redirect keeps the original URL indexed because Google expects it to come back.
Impact on Rankings
301 and 302 redirects handle rankings very differently. A 301 gives the destination URL the best shot at inheriting the original page’s position in search results. A 302 keeps the ranking equity tied to the old URL, which means the destination page starts from scratch.
When to Use Each One
| Situation | Use |
| Page permanently moved | 301 |
| Domain migration | 301 |
| HTTP to HTTPS switch | 301 |
| A/B testing a new page | 302 |
| Temporary promotion page | 302 |
| Geo or device based routing | 302 |
| Page under maintenance | 302 |
The Risk of Mixing Them Up
Using a 302 redirect where a 301 should be is one of the most common technical SEO mistakes out there. Google will keep crawling the old URL, the new page will not inherit any authority, and your rankings can stagnate for months before you even notice something is wrong.
When in doubt, ask yourself one question. Is this page coming back? If the answer is no, use a 301 redirect, every single time.
The SEO Risks of Using 301 and 302 Redirects Incorrectly
Getting 301 and 302 redirects mixed up is not just a minor technical slip. It can quietly damage your search performance in ways that take months to undo.
Here is what goes wrong when the wrong redirect type gets used:
- Link equity gets stranded. A 302 used in place of a 301 redirect means Google keeps the authority tied to the old URL. The new page builds nothing.
- Rankings stall or drop. If Google is not transferring equity through your 301 redirects, the destination page has no foundation to rank from.
- Crawl budget gets wasted. Incorrect 302 redirects keep old URLs in the crawl queue. Google keeps revisiting pages that should have been retired long ago.
- Index confusion builds up. Mixing up 301 and 302 redirects across a large site creates duplicate indexing issues that compound over time.
- Recovery is slow. Once Google has settled into a crawl pattern based on the wrong redirect type, correcting it takes multiple crawl cycles before the damage starts reversing.
The SEO impact of using 301 and 302 redirects incorrectly is rarely immediate. That is exactly what makes it dangerous.
Getting 301 and 302 Redirects Right Matters More Than You Think
301 and 302 redirects are two of the most straightforward tools in technical SEO, but only when used correctly. Permanent moves need a 301. Temporary ones need a 302. Swap them around and you are handing Google mixed signals while your rankings quietly take the hit.
The good news? Once you understand how 301 and 302 redirects work, making the right call becomes second nature. Audit your redirects, check your intent, and make sure every URL on your site is pointing in the right direction.
