301 (Moved permanently)
The requested page has been permanently moved to a new location.
This is bad for SEO. |

Well, this is not bad in itself, as everything in this world, http 301 can be good and bad.
So, a 301 redirection is just a redirection meant to be permanent. When bots follow such redirection, they drop the redirected url and consider the target url as the url to be used from now on. It can be very useful in many cases.
For example, 301 redirecting is involved in the www prefix redirection, and allow us to fully handle the www duplicate matter :
http://phpbb-seo.com is a duplicate of http://www.phpbb-seo.com and the problem is, this potentially mean a duplicate per page on the whole domain, but as you can see, if you get rid of the www prefix, you'll get redirected to the same url with the prefix. Here 301 is really useful, we use it for it's real meaning. Bots do get it very well, you'll never see any url without the www prefix in SERPS for the phpbb-seo.com domain.
Then, our zero duplicate mod uses as well 301 redirecting, to make sure no duplicate are used on phpBB forums :
http://www.phpbb-seo.com/boards/viewforum.php?f=10
http://www.phpbb-seo.com/boards/duplicate-vt2676.html
etc ...
In these cases, 301 redirecting are again very handy and useful.
What you would not want to do, would be for example to http 301 redirect your domain to another one by accident, because SE could end up dropping completely the domain in favor to the targeted one. But these cases are pretty rare actually, it's just a matter of using 301 redirection as they should.
As you can see, I have no fear to post links which will involve http 301 header here, because these example links really are meant to be forgotten as soon as they will be followed by bots (and user actually). |

| I was told by my senior that search engines value 301 redirections because they are permanent in nature, while they do not count 302 as it is temporary. I could not understand the concept. Do you know what it is? |

Header codes are just a standard to handle basic communication between client (bots, browsers ...) and servers, the full list can be found here : http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html
| Quote: | 302 Found
The requested resource resides temporarily under a different URI. Since the redirection might be altered on occasion, the client SHOULD continue to use the Request-URI for future requests |
| Quote: | 301 Moved Permanently
The requested resource has been assigned a new permanent URI and any future references to this resource SHOULD use one of the returned URIs. Clients with link editing capabilities ought to automatically re-link references to the Request-URI to one or more of the new references returned by the server, where possible. |
So, you can redirect using both headers, but it will not have the same meaning.
For example, the link to your private message http://www.phpbb-seo.com/forums/privmsg.php?folder=inbox is redirected to the login box with a 302 header when you are not logged in. It's pretty logical in this case, because the actual target is the pm box. Once logged in, you should still use the pm box url, it's not meant to be dropped, unlike the 301 example I posted above.
So, there is no general answer, 301 are good when they are properly used, when the permanent redirecting makes sens. |

thanks a lot,
that's a great amount of knowledge. I am sure now I understand a lot about 301.
Again...
what happens to the page rank of a webpage when it's redirected with a 301?
when does the new page normally attain the pagerank? |
