Choosing the wrong redirect type can hurt your site's SEO, confuse users, and even cause ranking drops. In this deep dive, you'll learn what 301 (permanent) vs 302 (temporary) redirects mean, when to use each, how search engines treat them, common mistakes, tools to test your redirects (including Divertidus’s Redirect Checker), and best practices to implement them correctly.

When you update a website structure, move content, or change URLs, redirects become essential. But there are different kinds—some permanent, some temporary—and choosing the wrong one can have real consequences for your website’s traffic, user experience, and search engine ranking.

Redirects are HTTP status codes that inform browsers and search engines how to treat old URLs. Two of the most common are 301 Moved Permanently and 302 Found (or temporarily moved). While they may seem similar, their implications are distinct.

In this guide, we’ll explore:

• What 301 and 302 redirects are and how they differ
• How search engines handle each
• When you should use 301 vs. 302 redirects
• Common mistakes webmasters make
• How to check your redirects (with Divertidus’s Redirect Checker and other tools)
• Best practices to maintain SEO while using redirects

By the end, you’ll know exactly which redirect to use and how to verify your redirects are configured correctly for SEO.

What Are 301 and 302 Redirects?

Definition of 301 Redirect (Permanent)

A 301 redirect is a permanent redirect. It tells browsers and search engines that the old URL has been permanently moved to a new URL. All traffic (users and bots) should go to the new place. Importantly, in the context of SEO:

• Search engines transfer the ranking power (sometimes called “link equity”) from the old URL to the new one.

• The new URL eventually replaces the old URL in search engine indexes.

 Definition of 302 Redirect (Temporary)

A 302 redirect indicates a temporary move. The original URL is expected to return or remain important. Key points:

• Search engines typically keep the old URL indexed (because they expect the redirect to be removed).

• Link equity is often not (or only partially) passed to the redirected URL, since it’s not permanent.

How Search Engines Treat 301 vs 302 Redirects

Understanding how Google and other search engines respond is crucial:

• Indexing and canonical signals: With a 301, once search engines process it, they will replace the old URL in the index with the new one. With a 302, they often leave the old URL in the index because they assume the old content may return.

• Passing ranking power/link equity: A 301 tends to transfer nearly all of the SEO value from the old page to the new one. For 302, transfer is limited or deferred. If a 302 is left in place too long, search engines might treat it like a 301.

• Caching behavior: Browsers often cache 301 redirects; meaning once a user has been redirected, repeat visits go directly to the destination without re-requesting the old URL. 302s are less likely to be cached as this is supposed to be temporary.

 When to Use 301 vs 302 Redirects

 Use 301 Redirects for Permanent Moves

Examples include:

• You change domain names (e.g., olddomain.com → newdomain.com).
• You move content to a new URL permanently (URL slug change, restructuring site).
• You consolidate several pages or remove obsolete ones.
• For HTTP → HTTPS migrations (you want all traffic permanently to move).

Using 301 ensures SEO value is preserved, rankings remain stable, and users/bookmarks forward correctly.

Use 302 Redirects for Temporary Situations

Examples include:

• Site maintenance or redesigns — you temporarily redirect visitors to a “maintenance mode” page.
• A/B testing two versions of a page.
• Seasonal or promotional pages that you’ll remove later.
• You want to test content without losing the original URL’s SEO value.

Important: do not leave a 302 redirect in place for too long. If it is permanent, switch to 301.

Common Mistakes with Redirects

1. Wrong Redirect Type
   People sometimes use a 302 when they meant a permanent move, leading to loss of SEO benefit. Conversely, using a 301 for temporary pages eliminates flexibility.
2. Redirect Chains & Redirect Loops
   • Chains: URL A → B → C → … The more hops, the slower the page and more chances of error.
   • Loops: A → B → A (infinite loop) breaks site usability and can cause errors.
3. Neglecting HTTP → HTTPS
   When migrating to HTTPS, some sites redirect pages individually without a global redirect — leading to mixed content, duplicate content, and SEO issues.
4. Failing to Update Internal Links
   Even if redirects are set, all internal links, sitemaps, canonical tags should point to the final URL to avoid unnecessary hops.
5. Leaving Temporary Redirects in Place Too Long
   A 302 left indefinitely might be treated like a 301 by search engines anyway, causing confusion.

How to Check Your Redirects

Verifying your redirects is as important as setting them correctly. Here are approaches & tools:

 Use Online Redirect Checker Tools

Some examples of tools you can use:

• Divertidus Redirect Checker (if you have or use such a tool) — enter your URL and see the status code, redirect type (301 vs 302), redirect chain, etc.
• Redirect Checker by Seobility, httpstatus.io, Redirect Detective, CheckSERP, etc. allow you to test one URL or multiple URLs.

Using Browser and Developer Tools

• Open browser, visit the URL, inspect with dev tools → Network tab → watch for HTTP status codes (301, 302)
• Check whether location headers are set correctly

 Using Command Line Tools

• curl -I http://old-url.com — fetches headers; you’ll see something like HTTP/1.1 301 Moved Permanently and a Location: header.
• On Linux/macOS, curl -L follows redirects; -I shows header info.

Checking Redirect Chains

• Tools like httpstatus.io or Divertidus can show full chains. For example: A → B → C → final URL.
• Remove unnecessary intermediate redirects to improve speed and SEO.

 Real-World Case Studies & Examples

 Migrating a Domain

Suppose Divertidus.com decides to change domain to Divertido.com:

• Setup 301 redirects from every page on Divertidus.com → equivalent page on Divertido.com
• Ensure HTTPS across both domains
• Update internal links, canonical tags, sitemap

Key measurement: monitor users, search console coverage, organic traffic to ensure ranking value flows.

 Seasonal Promotions

E.g. a retail site wants to temporarily redirect /sale → /holiday-sale. Use 302. After promotion ends, remove redirect and restore original /sale content.

If instead they use 301 by mistake, browsers may cache the redirect, causing issues when /sale is needed again permanently.

 Impacts on SEO & UX

• User Experience: Redirects help avoid 404s, broken links. Clean redirect helps with faster page load. Chained or poorly configured redirects slow things.
• Link Equity & Rankings: 301 helps preserve and transfer SEO value. 302 doesn’t (unless engines assume long-lived usage and treat it like 301).
• Crawl Budget: Excessive redirect chains waste crawling resources. Search engines have limited budgets.
• Page Load Time: Each redirect adds latency. Chaining multiplies. This can impact Core Web Vitals & ranking.

 Step-by-Step: How to Implement Redirects (on Server, CMS, etc.)

On Apache (.htaccess)

# Permanent redirect (301)
Redirect 301 /old-page.html https://divertidus.com/new-page.html

# Temporary redirect (302)
Redirect 302 /promo https://divertidus.com/temporary-promo

On Nginx

# Permanent
rewrite ^/old-page$ https://divertidus.com/new-page permanent;

# Temporary
rewrite ^/promo$ https://divertidus.com/temporary-promo redirect;

CMS Platforms (WordPress, Drupal, etc.)

• Use redirect plugins (Redirection, Yoast, etc.) — ensure you choose the correct type.
• Update menus, internal links, canonical URLs.
• Test after changes.

How Divertidus’s Redirect Checker Helps

If Divertidus.com offers a tool (or you link to such tool), emphasize:

• Instant check results for URL status code (301/302)
• View redirect chains and final destination
• Detect if wrong redirect type is being used

Best Practices for Redirect SEO

• Use 301 for any permanent URL changes
• Limit redirect chains (aim for one redirect where possible)
• Always redirect HTTP → HTTPS using 301 when moving to secure protocol
• Use canonical tags and sitemap updates
• Monitor redirects regularly (tools + Search Console)
• Keep redirects in place long enough (many recommend at least one year) for stability and link equity to transfer

Frequently Asked Questions (FAQ)

Q: What happens if I use a 302 redirect for a long time?
A: Search engines may eventually treat it like a 301, but there could be lost link equity and confusion. It’s better to switch to 301 if the change is permanent.

Q: Do 301 redirects always transfer 100% of SEO value?
A: Almost always, but some slight loss might occur depending on server response, caching, redirect chain length, and whether the redirect was implemented cleanly.

Q: Are there other redirect status codes I should care about?
A: Yes. For example, 307 Temporary Redirect, 308 Permanent Redirect, 404 Not Found, 410 Gone. But 301 and 302 are the most commonly used and well-understood.

Q: Can I check if a redirect is hurting my site’s SEO?
A: Yes — monitor Search Console (coverage & indexing), check traffic drops, test redirects with tools, inspect any redirect chains, and ensure new URLs are indexed.

Conclusion

Redirects are powerful tools—they let you move content, update your site, conduct promotions, and maintain user experience. But they must be used appropriately. Choosing between 301 (permanent) vs 302 (temporary) isn’t just a technical decision—it’s one that affects SEO, traffic, and site trust.
