SEO Impact
308 is the method-preserving equivalent of 301. Google explicitly treats 308 like 301 and consolidates link equity to the destination. Use it when you need a permanent redirect that must keep a POST method (rare in SEO, more common in API contexts). For typical HTML page redirects, 301 is more universally supported.
When to Use 308
Permanent API redirects where the HTTP method must be preserved across the redirect.
HTTP Response Example
