301 redirects are permanent, so they only need to be set up once. They can signal to search engines that a page has been permanently moved or removed, which can help boost website traffic in the process.
A 302 redirect is a permanent redirect, meaning that you are telling the browser to permanently send visitors from one page to another. In other words, it's a more permanent solution to 301 redirects.
