What is the core difference between 307 and 308?

Permanence. A 307 is a temporary redirect that leaves the original URL indexed, while a 308 is permanent and passes ranking signals to the destination. Both preserve the HTTP method.

Do 307 and 308 both keep a POST as a POST?

Yes. Method preservation is the feature both share. The choice between them is only about whether the move is temporary or permanent.

Which is the SEO-friendly one for a permanent move?

A 308. Like a 301, it passes ranking signals to the new URL. A 307 is temporary and keeps the old URL indexed, so it does not transfer ranking value.

307 vs 308

307 vs 308 redirect

A 307 and a 308 share one trait: both guarantee the request method survives the redirect, so a POST stays a POST. They are the method-preserving counterparts of the older 302 and 301.

What separates them is the same permanent-versus-temporary split that runs through the whole redirect family, and that split decides what happens to your rankings.

When to use a 307

Use a 307 for a temporary redirect that must keep the request method, such as briefly routing a POST endpoint elsewhere during maintenance without losing the body. The original URL stays indexed because the move is not permanent.

If the redirect is only ever for GET pages, a plain 302 does the same job; the 307 earns its keep when a method must be preserved.

When to use a 308

Use a 308 for a permanent redirect that must keep the request method, like permanently moving an API endpoint that accepts POST. It passes ranking signals to the destination just as a 301 does.

Think of a 308 as a 301 that also guarantees the method survives, which is exactly what you want for a permanently moved write endpoint.
