What is a 308 Status Code?

The 308 “Permanent Redirect”(3xx redirects) status code is not one of the original HTTP/1.x status codes, but it’s defined in RFC 7538, which is part of the HTTP extensions.

When a server returns this status code, it indicates that the target resource has been assigned a new permanent URI, and any future references to this resource should use one of the returned URIs.

It’s somewhat similar to a 301 “Moved Permanently” in its intention, but with an essential difference concerning the HTTP method used:

  • For a 301 “Moved Permanently”: When a GET or HEAD request initiates a redirection, the user agent (like a web browser) can change the HTTP method from POST to GET for the subsequent request. This behavior can cause issues if a POST request intended to make a change is redirected and the user agent switches to a GET request, potentially losing the data sent in the POST.
  • For a 308 “Permanent Redirect”: The user agent must not change the HTTP method used. If a POST was used in the first request, a POST must be used in the redirected request.

This makes 308 a safer choice in certain scenarios where the HTTP method and body must be preserved across the redirect.

308 Status Code SEO Implications

The 308 status code has specific implications for search engine optimization (SEO). When implementing any type of redirect, it’s crucial to understand the potential impacts on search performance and rankings. Here are the primary SEO implications of using a 308 status code”:

Link Equity Transfer Just like the 301 Moved Permanently, a 308 “Permanent Redirect” should pass almost all link equity (sometimes referred to as “link juice“) from the source URL to the target URL.
This is important for maintaining the search ranking power of the original URL.
Indexation Search engines should eventually replace the old URL with the new one in their indices.
Over time, as the search engines crawl and recognize the 308 code, the old URL should drop out of the index, and the new URL should appear in its place.
Preservation of HTTP Method The unique feature of the 308 compared to 301 is that the HTTP method (GET, POST, etc.) remains unchanged during the rerouting.
While this is more of a technical aspect than an SEO one, it can have indirect SEO implications. For example, if a form submission (using POST) on a site is redirected improperly with a 301, it might change to a GET request, leading to errors or unexpected behaviors that can negatively affect the user experience.
Poor user experience can, over time, impact SEO.
Crawling and Caching Because the 308 indicates a “Permanent Redirect”, search engines will treat it as a long-term change. This means that once they recognize the redirect, they’ll adjust their crawling accordingly and will also update their cached version of the page.
Implementation Cautions While the 308 can be beneficial in specific scenarios, it’s not as widely recognized or used as the 301. Ensure that all user agents, including all search engine crawlers, properly handle this status code.
Before fully implementing it, you might want to test with a few URLs to ensure there aren’t any unexpected behaviors.
Monitoring As with any major change on a website, it’s essential to monitor the site’s performance and search engine ranking after implementing changes.
Use tools like Google Search Console to track the indexing status of redirected URLs and to check for any crawl errors.

In conclusion, when used correctly, a 308 status code can effectively manage site changes without losing SEO value. However, it’s vital to use it in the right context and monitor its impact, just as with any other type of redirect.

What Does Google Say About 308 Redirects?

Both the 301 and 308 status codes have their merits, but the best choice largely depends on the specific use case. In general, if you don’t have a specific need to preserve the HTTP method, a 301 is likely the safer and more commonly accepted option. However, if method preservation is essential, then the 308 comes into its own.

Google treats the 308 status code similarly to other permanent redirects like the 301 “Moved Permanently” in terms of search behavior. This means that Google will typically pass link equity (or “link juice”) from the initial URL to the target URL and, over time, will replace the old URL with the new one in its index.

308 Status Code Common Issues and How to Fix Them

When managing a website, encountering various HTTP status codes is inevitable. Among them, the 308 code serves a specific purpose in ensuring users and search engines are directed to a new, permanent URL without changing the HTTP method. However, like all technology implementations, it’s not immune to hiccups.

Navigating potential issues and knowing how to troubleshoot them is crucial for maintaining a smooth user experience. In this guide, we’ll explore common challenges related to the 308 status code and provide actionable steps to resolve them.

Looping Redirects

The 308 status code could inadvertently cause a loop if the source URL directs back to itself or if there’s a chain of redirects that leads back to the original URL.

Check your redirect rules to ensure none of them references back to the source URL. Using browser developer tools or tools like Redirect Checker by Sitechecker can help you trace and visualize the redirect chain. Once identified, modify the redirect rule to point to the correct destination URL.

Incomplete Redirect Chains

Sometimes, a URL might go through multiple steps before reaching its final destination (e.g., URL A redirects to URL B, which then leads to URL C). These chains can slow down the user experience and might not pass full link equity.

Implement direct routing. Instead of having multiple chained redirects, ensure that URL A directly shifts to URL C. This can be done by revising the .htaccess file or the corresponding configuration on your server or content management system.

Incorrect or Missing Content on Target URL

After implementing the 308 status code, the content on the new URL might differ from the original, leading to user confusion or a decline in search rankings.

Verify that the destination URL displays the correct content. If not, either modify the content of the target page to match expectations or adjust the redirect to point to the most relevant page.

Search Engines Not Recognizing the Redirect

In some cases, search engines might not immediately recognize the 308 status code, causing the old URL to remain indexed.

Ensure the 308 status code is implemented correctly. You can also use the URL Inspection Tool in Google Search Console to request indexing for the new URL. Over time, the old URL should be replaced in search engine indices by the new URL.

Incompatibility with Certain Browsers or Bots

Some older browsers or bots might not handle the 308 code as expected.

Review your website's traffic and determine which user agents or browsers are significant for your audience. If many users or vital bots aren't supporting 308, consider using the more commonly recognized 301 “Moved Permanently” status code. Alternatively, implement user-agent detection and serve appropriate redirects based on the visitor's browser or bot.

Remember that after making any changes, it’s essential to clear any server or content delivery network (CDN) caches to ensure the latest configurations are in effect.
