301 vs 302 Redirect — The Difference That Costs Websites Their Rankings

“Before we start the main article, let me give you an essential pro-tip and a special bonus piece of advice from my personal experience: whenever you implement a redirect, never make it temporary—always choose a permanent redirect and use the 301 status code. This is by far the best practice if you have permanently changed a URL slug. If you alter a URL without setting up this 301 redirection map, your users and search bots will instantly hit a frustrating 404 Page Not Found error, destroying your rankings.”

Here’s a mistake that happens on websites every single week, usually made by developers who understand what redirects are but get the type wrong.

A page gets moved to a new URL. A redirect gets set up. Traffic keeps flowing, so everyone assumes it’s working. Months later, the page that used to rank on page one has dropped to page four — or vanished entirely. Nobody touched the content. Nobody lost backlinks. The only thing that changed was the type of redirect used.

Quick Answer: What’s the Difference Between 301 and 302?

A 301 redirect tells search engines a URL has moved permanently — it transfers ranking authority to the new URL and updates the search index. A 302 redirect signals a temporary move — search engines keep the original URL indexed and don’t pass ranking value to the destination. Using a 302 for a permanent change is the single most common redirect mistake that quietly damages rankings.

What Is a URL Redirect and Why Do You Need One?

A URL redirect is a server instruction that automatically sends visitors — and search engine crawlers — from one URL to a different one. The visitor types or clicks the old address, the server responds with a redirect status code, and the browser fetches the new address instead.

Redirects come up in several common situations:

• You changed a page’s URL slug
• You migrated from HTTP to HTTPS
• You moved your website to a new domain
• You deleted a page and want to send visitors to the closest relevant page
• You merged two URLs into one canonical version
• You restructured your site’s URL hierarchy

Without a redirect, visitors land on a 404 error. That also tells search engines the page is gone — meaning any accumulated ranking value disappears, and backlinks pointing to it lead nowhere.

What Is a 301 Redirect?

A 301 redirect — officially “Moved Permanently” in the HTTP specification — tells browsers and search engines that a URL has permanently moved. The key word is permanently.

When a search engine crawls a 301, it:

• Updates its index to replace the old URL with the new one
• Transfers ranking signals (link equity) from the old URL to the new one
• Eventually stops crawling the old URL and removes it from the index
• Sends future organic traffic directly to the new URL

This link equity transfer is exactly why 301 redirects are the correct choice for permanent moves. Every backlink pointing to your old URL carries ranking value — a 301 makes sure that value flows to your new URL instead of disappearing.

Use a 301 redirect when:

• Moving a page to a permanent new URL
• Migrating from HTTP to HTTPS
• Moving to a new domain permanently
• Consolidating duplicate URLs into one canonical version
• Any URL change where the original will never come back

What Is a 302 Redirect?

A 302 redirect — “Found,” commonly called a temporary redirect — tells browsers and search engines a URL has moved, but only for now. The original URL is expected to return.

When a search engine crawls a 302, it:

• Continues indexing the original URL
• Does not transfer ranking signals to the new URL
• Keeps crawling the old URL on future visits
• Expects the original to eventually go back to normal

This is exactly right for temporary situations — but actively wrong for permanent changes, since search engines deliberately hold onto the original URL’s authority instead of passing it along.

Use a 302 redirect when:

• Showing a temporary maintenance page
• Running an A/B test on a different URL
• Routing to a seasonal promotion page that will return to normal
• Geographic or language-based temporary routing
• Any situation where the original URL will genuinely come back

HTTP 301 vs 302: Side-by-Side Comparison

The Real-World SEO Consequence of Using the Wrong Type

Say you have a blog post that’s been live for two years. It ranks on page one for a keyword bringing in 3,000 visitors a month, with backlinks from 25 other sites pointing to it. That URL has real accumulated authority.

You restructure your URL and redirect the old one to a new address — but you use a 302, maybe because it was quicker to set up.

With a 302: Search engines keep indexing the old URL. The new URL gets almost none of the old page’s ranking signal. If the old URL eventually returns a 404, that authority is lost for good, since it was never transferred. Your page-one ranking degrades or disappears.

With a 301: The index updates, link equity transfers, and the new URL inherits the ranking position of the old one. Traffic continues. Backlinks still count. Your SEO investment is preserved.

The difference in outcome can mean months of lost traffic — from a single wrong digit in a server configuration.

How to Check Whether Your Redirect Is a 301 or 302

The fastest way is to run your URL through a dedicated website redirect checker. Paste in your old URL, run the check, and the tool traces every hop, showing the exact HTTP status code at each step.

If it shows 301, your redirect is permanent. If it shows 302, it’s temporary — and if that URL should have moved permanently, it needs fixing right away.

Manual check (browser method): Open Chrome DevTools (F12), go to the Network tab, check “Preserve log,” then visit your old URL. The first request in the log shows the status code — though this only shows one hop at a time and is slower than using a dedicated checker.

Beyond 301 and 302 — Other Redirect Codes to Know

307 — Temporary Redirect (Method-Preserving): Behaves like a 302, but preserves the original HTTP method (POST, PUT, DELETE) instead of switching to GET. Matters for API endpoints and form submissions. For SEO purposes, it behaves like a 302 — temporary, no ranking transfer.

308 — Permanent Redirect (Method-Preserving): The modern, method-preserving equivalent of a 301, used where preserving the original request method matters.

303 — See Other: Redirects the browser to a confirmation page using GET after a form submission, preventing the “resubmit form?” prompt on refresh.

HTTP Status Code Reference Table

The HTTPS Redirect — A Special Case Worth Getting Right

Every website today should run on HTTPS, and the HTTP-to-HTTPS redirect is one of the most common redirects on the web — with one very specific correct setup.

Correct: http://example.com → https://example.com (one hop, 301 permanent)

Wrong — unnecessary double hop: http://example.com → http://www.example.com → https://www.example.com

Wrong — using 302 for HTTPS: tells search engines the HTTPS version is temporary, which keeps the HTTP version indexed alongside it and creates a canonical URL conflict.

HTTPS redirects should always be 301, completing in exactly one hop. Verify yours with the redirect checker — enter your http:// URL and confirm a single 301 hop lands directly on the HTTPS version.

How to Implement Correct Redirects on Different Platforms

WordPress: Most SEO plugins (Yoast, RankMath, the Redirection plugin) let you set redirects from the admin panel. Always confirm the type is set to 301 for permanent changes before saving. For server-level performance, add redirects directly to .htaccess:

Redirect 301 /old-page https://example.com/new-page

Apache (.htaccess):

apache

# Single permanent redirect
Redirect 301 /old-page https://example.com/new-page

# HTTP to HTTPS (one hop)
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

NGINX:

nginx

server {
    listen 80;
    return 301 https://example.com$request_uri;
}

Shopify and hosted platforms: Most hosted platforms handle HTTPS redirects automatically. For custom URL redirects, use the platform’s built-in redirect manager — Shopify’s URL redirects default to 301.

Redirect Chains — When Multiple Redirects Stack Up

A redirect chain happens when your redirect destination itself redirects somewhere else: A → B → C. The browser makes three requests instead of one to reach the final page.

How chains typically form:

1. You set up A → B when you first change a URL
2. Later, you change B to C and set up B → C
3. Now anyone visiting A goes through two hops instead of one
4. This compounds as more URL changes accumulate over time

The fix: Update the earliest redirect to point directly to the final destination — A should redirect straight to C, bypassing B entirely. Our redirect chains guide covers this in more depth, including how to trace and flatten longer chains.

Checklist: Verifying Your Redirects Are Correct

• Run the old URL through a redirect checker — confirm the status is 301, not 302
• Verify the redirect completes in one hop, not a chain of two or more
• Check that your HTTPS redirect is 301 and completes in one hop
• Confirm www and non-www versions redirect to your canonical domain
• Make sure no redirect loops exist
• Confirm 302 is only used for genuinely temporary redirects
• Verify the HSTS header is present on your HTTPS pages
• After any site migration, check all important pages systematically
• Check redirects for your most important backlink destinations
• Re-verify redirect setup after any server or platform change

Frequently Asked Questions

Does a 301 redirect pass full ranking authority to the new URL? Yes. Search engines pass full link equity to the destination URL with a correctly implemented 301 — there’s no inherent penalty for using one.

What happens if I accidentally used a 302 instead of a 301? Change it to a 301 as soon as possible. The URL will be re-crawled and re-evaluated. Recovery time depends on how often your site is crawled — typically days to weeks for well-indexed sites.

Can I check redirect types in Google Search Console? Search Console shows indexing status and can surface redirect-related issues, but it doesn’t directly display the specific status code. A dedicated redirect checker gives you that detail instantly.

Do redirect chains hurt SEO? Yes, mainly by adding load latency and increasing crawl overhead. Search engines have softened their stance on minor link-equity loss within short chains, but a single-hop redirect is still the safest choice.

What is a redirect loop? A loop happens when URL A redirects to URL B, which eventually redirects back to A — causing a “too many redirects” browser error. It’s usually caused by conflicting rules in .htaccess or plugin settings.

How do I fix a www to non-www redirect? Set up a 301 redirect at the server or DNS level pointing all www requests to non-www (or vice versa), then confirm with a redirect checker that it completes in one hop.

Key Takeaways

The difference between a 301 and a 302 is one digit — but the SEO consequences of getting it wrong can last for months. Search engines do exactly what you tell them: say a move is temporary, and they’ll hold onto the original URL’s authority instead of transferring it.

For any permanent change — domain migration, URL restructuring, HTTP-to-HTTPS — use a 301. For genuinely temporary situations — maintenance pages, A/B tests, seasonal routing — use a 302.
