The Basics
What is a 301 Redirect?
Status Code: 301 Moved Permanently
Definition: Tells browsers and search engines that a page has permanently moved to a new location.

What is a 302 Redirect?
Status Code: 302 Found (Temporary Redirect)
Definition: Indicates a temporary move. The original URL should still be used for future requests.
Example:
HTTP/1.1 302 Found
Location: https://example.com/temp-page

SEO Impact Comparison
301 Redirect SEO Effects
✅ Positive Effects:
- Link Equity Transfer: 90-99% of PageRank passes through
- Index Update: Search engines replace old URL with new
- Ranking Preservation: Rankings typically maintained
- Consolidated Authority: Combines signals from both URLs
⚠️ Considerations:
- Takes time (2-6 months for full transfer)
- Should remain in place for at least 1 year
- Some slight ranking fluctuation is normal
- Must update internal links
Timeline:
Week 1-2: Search engines discover redirect
Week 2-4: Link equity begins transferring
Month 2-3: Old URL drops from search results
Month 3-6: Full equity transfer complete
302 Redirect SEO Effects
Impact:
- No Link Equity Transfer: SEO value stays with original URL
- Original URL Stays: Keeps appearing in search results
- Temporary Signal: Search engines keep checking original
- No Ranking Transfer: New page doesn’t inherit rankings
Best For:
- Testing without SEO impact
- Temporary promotions
- Maintenance modes
- Preserving original URL rankings
When to Use 301
✅ Perfect Use Cases:
1. Domain Migration
Moving from old domain to new domain:
❌ Bad: example-old.com → example-new.com (302)
✅ Good: example-old.com → example-new.com (301)
Why: You want to transfer all SEO value, rankings, and authority to the new domain.
2. Site Restructuring
Changing URL structure:
Old: /blog/2024/10/30/post-title
New: /blog/post-title
Redirect: 301
Why: Old URLs aren’t coming back. You want search engines to index the new structure.
3. HTTPS Migration
Forcing secure connections:
http://example.com → https://example.com (301)
Why: HTTP version is permanently deprecated. All traffic should use HTTPS.
4. Consolidating Duplicate Content
Canonical URL enforcement:
example.com → www.example.com (301)
www.example.com/index.html → www.example.com (301)
Why: Prevents duplicate content issues and consolidates SEO signals.
5. Retired Product/Service
Redirecting to alternative:
/old-product → /new-product (301)
Why: Old product isn’t returning. Users should find the replacement.
6. Merged Pages
Combining related content:
/page-a → /combined-page (301)
/page-b → /combined-page (301)
Why: Content permanently consolidated. Want to combine SEO value.
When to Use 302
✅ Perfect Use Cases:
1. A/B Testing
Testing new page versions:
/page → /page-variant-b (302)
Why: Original page will return. You don’t want search engines indexing test pages.
2. Seasonal Promotions
Holiday or sales redirects:
/products → /black-friday-sale (302)
Why: Promotion is temporary. Original URL returns after the event.
3. Maintenance Mode
During site maintenance:
/* → /maintenance.html (302)
Why: Site will return to normal. Don’t want maintenance page indexed.
4. Geographic Redirects
Location-based redirects:
/store → /store-us (302)
/store → /store-uk (302)
Why: Users return to original URL, then get redirected based on location.
5. Testing New Content
Evaluating page performance:
/landing-page → /landing-page-new (302)
Why: Testing performance before making permanent. May revert.
6. Login Redirects
After authentication:
/login → /dashboard (302)
Why: Login page still exists and is accessed regularly.

Advanced Considerations
Cache Control
For 301 (Permanent):
HTTP/1.1 301 Moved Permanently
Location: https://example.com/new
Cache-Control: max-age=31536000, public
Aggressive caching improves performance.
For 302 (Temporary):
HTTP/1.1 302 Found
Location: https://example.com/temp
Cache-Control: no-cache, no-store, must-revalidate
Prevents stale redirects after removal.
User-Agent Considerations
Some sites serve different redirects for:
- Desktop vs mobile
- Bots vs real users
- Different search engines
Best Practice: Be consistent unless intentionally varying.
FAQ
Q: Can I change a 302 to 301 later?
A: Yes! If you determine a “temporary” redirect is actually permanent, update to 301.
Q: How long should I keep 301 redirects active?
A: Minimum 1 year, ideally forever. Costs minimal server resources.
Q: Does 301 pass 100% of SEO value?
A: Google says ~90-99%. Small loss is normal and acceptable.
Q: Can 302 hurt SEO?
A: Not if used correctly for temporary changes. Problems arise when misused for permanent moves.
Q: What if I’m not sure if change is permanent?
A: Use 302 initially. Convert to 301 if it becomes permanent.
Q: Do redirect chains matter?
A: Yes! Minimize chains:
- ❌ A → B → C (Bad)
- ✅ A → C (Good)
Each hop adds latency and potential link equity loss.
Conclusion
Golden Rules:
- Use 301 for permanent moves - migrations, restructuring, retired content
- Use 302 for temporary changes - testing, promotions, maintenance
- Test your redirects - verify status codes are correct
- Monitor performance - check search rankings after implementation
- Keep redirects active - minimum 1 year for 301s
- Update internal links - don’t rely on redirects internally
Still unsure? When in doubt:
- If it might be permanent → use 301
- If definitely temporary → use 302
