Welcome to the Q&A Forum

Yes, you should. Here is a better definition for you: 302 redirect shall be used when the original URL was working as a normal web page, but then for some reason that page needed to be redirected for, let's say, next 24 hours only. An example would be if you are redesigning an existing page of a website and need to redirect users to another page for a few days so that users do not see the mess while you redesign. 301 redirect is pretty much when the original URL is not going to exist anymore, as in telling google to not check, not to render, not to try to index that URL. Actually, I have a better question - since these temporary URLs are indeed temporary, why to even have them? and not just have straight forward normal URLs? It's not like those temporary URLs will be ever ranking..
