Please read this article about 301 redirects. Hope it helps you.

301 redirect is the best seo method for website or page redirection.

Let me tell you about all redirect...

301 = Permanent redirect
"It's not here any more, I moved it there, get it from there."
The proper HTTP response is to request the document from there.

302 = Undefined redirect
"Uh, it's not here, I moved it there, not sure why, not sure for how long, not sure if I will move it back."
The proper HTTP response is to continue requesting the document from here.

307 = Temporary redirect
"It's not here right now, I moved it there, but it will be back, so keep checking for it."
The proper HTTP response is to continue requesting the document from here.

If you are moving a page temporarily, I would suggest using the proper status code when you have the ability.

Similarly:

404 = Not Found
"Oops! No file. Looking here on the desk but don't see it, maybe I put it somewhere else. I'll let you know."
The proper HTTP response is to continue requesting the document.

410 = Gone
"Stop asking, I threw it away."
The proper HTTP response is to stop requesting the document.
