308 Redirect.

A 308 Permanent Redirect is the method-preserving equivalent of a 301. It tells the client that the resource has permanently moved to a new URL and that future requests should use the new URL—while also guaranteeing the original HTTP method (POST, PUT, PATCH) is preserved in the redirect, unlike a 301 which browsers typically convert to a GET.

When 308 Appears in SEO Contexts

308 redirects are most common in API-first architectures and HTTPS migration configurations. Some CDNs and load balancers issue 308s when enforcing HTTPS upgrades on non-GET requests. From a crawling perspective, Googlebot treats 308 similarly to 301—as a permanent signal that the original URL has moved and that link equity should transfer to the destination.

Practical Use

For standard HTML pages and marketing content, 301 remains the conventional choice for permanent redirects and has broader browser compatibility. Use 308 specifically when you have POST or PUT endpoints that need permanent redirection with method preservation—not for typical SEO redirect chains or page migrations.
