308 Redirects: A Guide to Permanent Redirects for SEO

Let's make the complex feel simple... and when it comes to SEO, understanding how redirects work can be a game changer for your website's performance. If you’ve ever dealt with website migrations or URL restructuring, you’ve likely heard of 301 redirects—but what about 308 redirects? While not as commonly discussed, a 308 redirect can be just as essential for ensuring the SEO health of your site. In this guide, we'll dive deep into what 308 redirects are, how they work, and why they’re important for your SEO strategy.

Whether you're running an e-commerce site, a blog, or a business website, maintaining a clean URL structure and ensuring proper redirection of old pages is critical for keeping your site’s traffic intact. The SEO impact of using the right redirect can’t be overstated, and in this post, we’ll show you how the 308 redirect plays a role in that equation.

What is a 308 Redirect?

A 308 redirect is a type of permanent redirect that, like the more widely known 301 redirect, sends visitors and search engines from one URL to another. However, there’s a key difference between the two: while both are used for permanent redirects, a 308 redirect specifically preserves the HTTP method (such as POST or PUT) during the redirect process. This means that the type of request your server originally received won’t be changed, making it a better option in certain situations.

Essentially, a 308 redirect tells search engines and browsers that a resource has permanently moved, but it ensures that any data submitted via POST remains intact. This can be critical for forms, e-commerce transactions, and other interactive features on your website. The 308 status code is part of the HTTP/1.1 standard and is used primarily when you need to maintain the integrity of specific HTTP methods, especially during a site migration or when implementing URL changes for specific pages.

Why Should You Care About 308 Redirects?

SEO professionals often focus on the importance of using 301 redirects, but 308 redirects should not be overlooked, especially if you’re dealing with POST requests or other scenarios where the HTTP method needs to stay intact. Here are some key reasons why you should care about 308 redirects:

  • Preserves POST Data: Unlike a 301 redirect, which can alter the HTTP method (often defaulting to GET), a 308 redirect keeps your POST data intact. This is crucial if you're redirecting a page that processes form submissions, transactions, or any other type of data entry.
  • SEO Integrity: A 308 redirect, being a permanent redirect, ensures that search engines understand the URL has been moved permanently. This helps search engines transfer link equity (the value passed through links) from the old URL to the new one, preserving your site’s SEO strength.
  • Future-Proofing: While 301 redirects are widely supported, a 308 redirect offers an alternative for scenarios that require a more stringent and reliable redirection method. It's especially useful for situations where you don’t want the redirected page’s HTTP request method altered.

When to Use a 308 Redirect

While 308 redirects can be powerful, they aren’t necessary for every situation. You should consider using them in the following scenarios:

  • Form Submission Redirects: If you need to redirect a page that handles form submissions (such as a contact form or payment processing page), a 308 redirect ensures that the POST method stays intact.
  • URL Changes with Complex Methods: If you're restructuring your site and need to redirect pages that handle complex HTTP methods (like POST or PUT), a 308 redirect ensures these methods aren’t lost in the process.
  • Site Migration: When migrating to a new domain or restructuring your website’s URLs, a 308 redirect can ensure that both your visitors and search engines are directed properly without losing the integrity of critical HTTP methods.

How to Implement a 308 Redirect

Implementing a 308 redirect is fairly simple, especially if you're familiar with handling redirects on your server. Here’s a basic example for how you might set up a 308 redirect using Apache or Nginx:

  • Apache: In your .htaccess file, you can use the following code:
Redirect 308 /old-page https://www.yoursite.com/new-page
  • Nginx: In your Nginx server configuration file, you can use:
    • rewrite ^/old-page$ https://www.yoursite.com/new-page permanent;

    In both cases, these lines of code will instruct your server to permanently redirect visitors from the old page to the new one, while preserving the HTTP method.

    Common Mistakes to Avoid with 308 Redirects

    While 308 redirects are a useful tool, they come with their own set of potential pitfalls. Here are some mistakes to avoid:

    • Overuse of Redirects: Too many redirects, whether 301, 302, or 308, can slow down your website’s performance and hurt your SEO. Keep your redirect chains as short as possible to avoid this.
    • Forgetting to Update Internal Links: When using redirects, don’t forget to update your internal links to point directly to the new URL. Relying solely on redirects can lead to unnecessary server load and slower performance.
    • Confusing Redirects with Temporary Redirects: Make sure you're using the correct redirect type for your needs. A 308 redirect is permanent, whereas a 302 redirect is temporary. Using the wrong type can confuse search engines and impact SEO.

    With that said, implementing 308 redirects correctly can be a powerful tool for maintaining SEO integrity and ensuring a smooth user experience on your site. When in doubt, consult with an SEO professional to make sure your redirection strategy aligns with your long-term goals.

    Conclusion

    308 redirects are a powerful yet underutilized tool in the world of SEO. By ensuring the preservation of HTTP methods like POST or PUT during a redirect, these permanent redirects help businesses maintain functionality, optimize SEO, and protect the user experience. Understanding when and how to use 308 redirects is crucial for any website owner who wants to optimize their site’s performance, especially when migrating or restructuring URLs. Remember, SEO is not just about driving traffic—it’s about keeping your visitors happy and your site functioning smoothly.
