You might want to use a 302 redirect when the content is redirected to some other URL temporarily. Examples include during website maintenance, such as A/B testing or running a promotional campaign.

A 302 redirect, unlike a 301 redirect, indicates to the search engines that the move is not permanent and, eventually, will return to the original URL. It might not pass the same link equity as in 301 redirect even though the user is directed.

Therefore, a 302 redirect should be used for temporariness. An example of misuse would be using a 302 for a permanent move because search engines might be stuck to see the new URL as the primary source rather than the old URL.
