302 vs. 301 redirect: Why you need to use a 301
So whats is in a redirect? Does it matter if it is a 302 redirect or a 301 redirect? Yes! Very much so. A 301 redirect informs Google that you are permanently moving a page to this new destination whereas a 302 redirect lets Google know this is only temporary. There is a time for a 302 and a time for a 301. If you are migrating a website across to a new one, say a .com to a .co.uk, you must use a 301 redirect.
