When managing a website, choosing the correct type of redirect is crucial for maintaining a seamless user experience and preserving SEO performance. Two primary redirect types, 301 redirects (permanent) and 302 redirects (temporary), serve distinct purposes, and selecting the wrong one can negatively impact your site’s rankings and traffic.
In this comprehensive guide, we’ll explore the differences between 301 and 302 redirects, their use cases, and how they influence your website’s search engine optimization (SEO).
Understanding HTTP Response Status Codes
When a browser (e.g., Chrome, Safari) or a search engine like Google requests a webpage, the server responds with an HTTP status code. These codes communicate whether the request was successful or encountered an issue.
Categories of HTTP Response Codes:
- 1xx (Informational): The request is received and being processed.
- 2xx (Success): The request is successful, and the server delivers the requested content.
- 3xx (Redirection): The requested page has moved, requiring redirection.
- 4xx (Client Errors): There’s an issue with the request, such as a 404 (Not Found) error.
- 5xx (Server Errors): The server failed to fulfill the request.
Since 301 and 302 redirects fall under the 3xx category, they signal a change in the URL structure, guiding users and search engines to the appropriate destination.
What Are 301 and 302 Redirects?
Both 301 and 302 redirects inform browsers and search engines that a webpage has moved to a new URL. However, they differ in how search engines handle indexing and ranking.
Why Use Redirects?
- Establish a canonical URL (e.g., redirecting http://example.com to https://www.example.com).
- Guide users to the correct updated or new page.
- Ensure visitors access the HTTPS-secured version of your site.
- Fix broken or deleted pages by redirecting users to an active page.
- Maintain SEO equity by transferring ranking power to a new page.
Using the wrong redirect type can hurt your site’s search rankings, traffic, and user experience.
What Is a 301 Redirect?
A 301 redirect is a permanent redirection that tells search engines to transfer all ranking power, link equity, and SEO value from the old URL to the new one.
When to Use a 301 Redirect
- Changing a URL permanently (e.g., rebranding or restructuring site URLs).
- Fixing broken pages (404 errors) to maintain traffic.
- Switching to a new domain (e.g., migrating from oldsite.com to newsite.com).
- Merging duplicate or similar pages for better SEO performance.
- Redirecting campaign landing pages after a promotion ends.
- Directing misspelled or alternative domain names to your main site.
- Enforcing a preferred domain (e.g., www.example.com vs. example.com).
SEO Impact of 301 Redirects
- Passes nearly 100% of link equity to the new URL.
- Preserves search rankings after URL changes.
- Helps Google update its index with the new URL over time.
What Is a 302 Redirect?
A 302 redirect is a temporary redirect that tells search engines that the original URL will be restored in the future.
When to Use a 302 Redirect
- Testing or updating a page while temporarily redirecting users.
- Running an A/B test to compare different versions of a webpage.
- Temporarily promoting a different landing page for an event or campaign.
- Redirecting traffic during site maintenance or downtime.
- Seasonal content management, such as holiday sales pages.
SEO Impact of 302 Redirects
- Does not transfer link equity to the new URL.
- Original page remains indexed, preventing Google from treating the change as permanent.
- Useful for short-term changes but should not be used for permanent URL moves.
How 301 and 302 Redirects Affect SEO
Search engines handle 301 and 302 redirects differently, impacting ranking, link equity, and indexing.
| Feature | 301 Redirect | 302 Redirect |
| Type | Permanent | Temporary |
| Link Equity Passed | ✅ Yes | ❌ No |
| Affects SEO Rankings | ✅ Yes | ❌ No |
| Indexing Effect | Replaces old URL | Keeps old URL indexed |
Using a 302 redirect instead of a 301 for permanent changes can harm rankings because Google won’t pass ranking authority to the new page.
How to Implement Redirects
Google recommends setting up redirects at the server level to ensure proper indexing and SEO preservation.
Server-Side Redirects
For Apache servers, add the following .htaccess rule for a 301 redirect:
Redirect 301 /old-page.html https://example.com/new-page.html
For Nginx servers, use:
rewrite ^/old-page.html$ https://example.com/new-page.html permanent;
For Microsoft IIS, configure redirects through the IIS Manager.
WordPress Redirect Plugins
- Redirection (for managing 301 redirects and tracking 404 errors).
- Simple 301 Redirects (for quick and easy permanent redirects).

Best Practices for Using Redirects
- Use 301 redirects for permanent changes to preserve SEO rankings.
- Use 302 redirects only for temporary situations.
- Avoid redirect chains (multiple redirects in a row) as they slow down page loading.
- Regularly audit your site to ensure old redirects are still relevant.
Final Thoughts
Understanding the differences between 301 and 302 redirects is essential for maintaining your website’s SEO authority and user experience. By choosing the correct redirect type, you ensure that your site retains its search rankings, traffic, and credibility.
By implementing proper redirect strategies, you can enhance your website’s SEO while keeping users engaged and search engines properly indexing your content.
