301 and 308 redirects are both essential tools in SEO, used to guide users and search engines from one URL to another. The primary difference lies in their handling of HTTP methods: a 301 redirect changes the request method to GET, while a 308 redirect preserves the original request method.
What is a 301 Redirect?
A 301 redirect is a permanent redirect that informs search engines and users that a page has moved to a new location. It is the most commonly used redirect in SEO due to its ability to pass on the majority of the original page’s link equity. This means that the SEO value is transferred to the new page, helping maintain search rankings.
Benefits of 301 Redirects
- SEO Value Preservation: Transfers up to 90-99% of the original page’s SEO value to the new page.
- User Experience: Seamlessly directs users to the updated URL without interruption.
- Search Engine Indexing: Informs search engines to update their index with the new URL.
What is a 308 Redirect?
A 308 redirect is also a permanent redirect, but it differs in that it maintains the original HTTP request method. This means if the initial request was a POST, the redirect will also be a POST. Though less commonly used, it is crucial when preserving the request method is necessary.
Benefits of 308 Redirects
- Preserves HTTP Method: Keeps the original request method, which is essential for certain web applications.
- Permanent Redirect: Like a 301, it tells search engines to update their index to the new URL.
- SEO Value: Similar to 301, it can also pass on SEO value, albeit with less documentation on its effectiveness.
Key Differences Between 301 and 308 Redirects
| Feature | 301 Redirect | 308 Redirect |
|---|---|---|
| HTTP Method | Changes to GET | Preserves original method |
| SEO Value Transfer | High | High (though less documented) |
| Use Case | General URL changes | Method-sensitive applications |
| Commonality | Widely used | Less common |
When to Use 301 vs. 308 Redirects?
Choosing between a 301 and a 308 redirect depends on the specific needs of your website and application requirements.
-
Use 301 Redirects when you need a straightforward, permanent URL change with no need to preserve the request method. Ideal for SEO value retention and general URL updates.
-
Use 308 Redirects when the application requires the original request method to be maintained. This is particularly relevant for applications where POST requests are crucial.
Practical Examples
-
301 Redirect Example: If you’ve permanently moved a blog post to a new URL, a 301 redirect will ensure that users and search engines are directed to the new location, maintaining SEO value.
-
308 Redirect Example: If an e-commerce site needs to redirect a checkout POST request to a new URL, a 308 redirect will preserve the POST method, ensuring the transaction continues seamlessly.

For a website redesign where URLs are changing, a 301 redirect is usually the best choice. It will help maintain the SEO value of your pages and ensure users are directed to the correct new URLs.
Conclusion
Both 301 and 308 redirects serve essential roles in SEO and user experience. Understanding their differences helps in choosing the right redirect for your needs. For most general purposes, a 301 redirect is sufficient for maintaining SEO value and ensuring users find the new page. However, when preserving the HTTP method is necessary, a 308 redirect is the better choice. Always evaluate the specific requirements of your website or application to decide which redirect will best serve your goals.
