Common redirect codes
301 redirect (Moved Permanently) — the resource has a lasting new location. Search engines treat this as a permanent move and typically consolidate signals toward the destination. It is the usual choice for a migration or a merge of two pages.
302 Found — a temporary move. Useful for short-lived tests; not the usual choice when you want a permanent consolidation. 303 See Other usually tells the client to fetch the result at another address with a GET. 307 Temporary Redirect is temporary but keeps the original request method. 308 Permanent Redirect is permanent and keeps the original method. Together these 3xx status codes are what this tool follows, and each one shows its redirect code in the table.
