301 vs 302 Redirects
301 vs 302 redirects are the first redirect choice most teams need to get right. The difference is simple. A 301 is permanent. A 302 is temporary.
Simple answer: Use a 301 when the URL moved for good. Use a 302 when the original page may return later.
- What 301 and 302 mean
- When to use each code
- How search systems read the choice
- What to check after launch
- Why mixed signals waste time
Plain meaning: this lesson connects the beginner definition to the business system Groew builds around it.
A 301 and a 302 say different things about the same route move
A 301 tells browsers and search systems that the old URL has a new permanent home. The old address should stop being the main version. The new one should own the page from now on.
A 302 tells the same systems that the move is temporary. The original URL still matters. It may return, or the team may change the route again after a short period.
That difference is the whole decision. The code is not decoration. It is a signal about what the business actually intends.
Permanent and temporary routing solve different problems
A 301 is the normal choice when a page moves for good, two pages merge or the old path should disappear from active use. A 302 is the better fit when the old URL is only paused, tested or borrowed for now.
If the team uses a 302 for a page that has clearly moved forever, the site keeps a temporary signal for no reason. If the team uses a 301 for a page that may come back, the site sends a final signal too soon.
The right choice keeps users, crawlers and internal teams on the same story.
| Situation | 301 fit | 302 fit |
|---|---|---|
| Permanent page move | Yes | No |
| Short maintenance window | No | Yes |
| Merged content | Yes | No |
| Page may return later | No | Yes |
Search systems use the redirect type as part of the story
Google Search Central says redirects are part of the site move process. MDN describes a 301 as permanent and a 302 as temporary. That means the status code is one of the first clues search systems get about the new route.
The clue works best when the rest of the site agrees. Internal links, canonical tags and sitemap entries should support the same destination instead of sending mixed signals.
A redirect should help the system settle on the right URL, not make it guess which URL is real.
The old URL, the destination and the supporting signals all need one clean answer
After launch, test the old URL and confirm it lands on the intended page in one hop. Then check the destination page itself. It should load normally and match the reason for the redirect.
If the route is chained, shorten it. If the canonical tag still points somewhere else, fix it. If the sitemap still lists the wrong page, update it.
A clean redirect is never only one line in the server config. It is a full route decision.
The common mistake is choosing the code by habit instead of by business meaning
Teams often pick a 301 because it feels more final or a 302 because it feels safer. That is the wrong way around. The code should follow the actual state of the page, not the mood of the launch.
Another mistake is leaving a temporary redirect in place after the temporary reason ends. Once that happens, the site is carrying a signal that no longer fits reality.
The route should be reviewed again as soon as the original page state changes.
Redirect choice matters because old demand still has value
A redirect often protects existing traffic, bookmarks and links. That value is part of the asset the business already earned. The server code should protect it instead of scattering it across mixed route rules.
Groew treats that choice as Revenue Infrastructure because search growth depends on routes that say what they mean. A permanent move should look permanent. A temporary move should stay temporary.
When the code and the business job match, the site is easier to trust and easier to manage.

Search standards to keep in mind
Use these rules as guardrails before changing page structure, links or crawl settings. They keep the lesson connected to current search standards instead of one off tactics.
The biggest redirect mistake I see is not the code choice itself. It is when the team ships a route change and leaves the rest of the site arguing with it. In one recovery, the site had more than 200 technical errors before the foundation was repaired and the decline stopped within 90 days. The lesson is stable. Pick the right status code, then make every other signal agree.
