A mixed redirect is when there are 2 or more other URL redirects strung together in a chain, but the HTTP status is not the same for all redirects. At least one redirect in the chain is a 301 permanent redirect and at least one redirect in the chain is a 302 temporary redirect.

Both a 301 and 302 redirect are used for different purposes, and each sends a different message to search engines. If they are both used in the same chain, search engines will not know how to treat the URLs:

  • Is it actually a temporary redirect or a permanent one?

  • Should we remove the URL from our index or leave it?

  • Do we pass link juice to the target URL or not?

Therefore, we cannot predict how search engines will treat these URLs, and unintended consequences could result. Mixed redirects should be avoided.
