308 Redirect
308 is a permanent redirect that preserves the HTTP method (POST stays POST). It’s a stricter semantic alternative to 301.
Definition
308 Permanent Redirect is a permanent redirect status code similar to 301, but it explicitly preserves the HTTP method and body (e.g. POST won’t turn into GET). For SEO, both 301 and 308 are permanent redirects used to consolidate URL variants and migrate content.
Why it matters
- Consolidates URL variants (http→https, www, trailing slash)
- Transfers indexing and ranking signals to the new URL
- Better semantics when preserving HTTP methods matters
How to implement
- Redirect old URLs permanently to the new URL (avoid chains)
- Update internal links and sitemaps to the final URL
- Ensure the destination returns 200 and has correct canonicals
