For 301 redirects, I believe many stationmaster is not unfamiliar, in Google Administrator tool help below have such a passage

The 301 redirection feature is especially useful in the following situations:

You have moved your Web site to a new domain, and you want to do it as smoothly as possible.

People visit your site through different Web sites. For example, if you can access your home page in a variety of ways, such as Http://example.com/home, http://home.example.com, or http://www.example.com, choose one of them as your preferred (standard) Target URL, and through 301 redirect traffic from other sites to the preferred URL, is a good way. You can also use the Webmaster tools to set the preferred domain.

You are merging two Web sites, and you want to make sure that links to expired URLs are redirected to the correct pages.

But I found that a lot of webmasters are only used to change the domain name or a site has two domain names when the use of 301 redirect, but ignored Google help in the second description. In fact, Google Administrator tool the second help for us in the site optimization, especially the site PR value of the promotion is particularly important. The following old Xu I specifically to explain to you:

Google Admin Tool The second is to tell us not only in the site has two domain name when used to 301 redirect, for us only a domain name site should do a 301 redirect. We think that we have only one domain name site is not the case

These links all point to the same page (Xutao Site Optimization Blog homepage):

http://www.xutaoblog.com/

http://xutaoblog.com/

Http://www.xutaoblog.com/default.asp

But the process of sending a request from a URL and returning it to the content of the Web page, these URLs are different. Completely different content can be returned for the above Urls,web server. When the URLs correspond to the same content (usually the same). This leads to: Your site's main domain name of the PR value spread to several other URLs.

Google in the inclusion of your site needs to choose a representative from the above URLs, and ignore the rest. So the URL that was chosen by Google is a standardized URL. The process Google chooses is called "standardization". If you redirect the other three URLs to: www.xutaoblog.com So Google will know that the URL,PR you want is focused on the main URL:www.xutaoblog.com.

The above is the site optimization is ignored by the 301 redirect to the meaning of the URL standardization. (Tip: A friend who won't do a URL turn can look at the article I've collected online: Teach everyone about 301 redirects and how to do 301 redirects http://www.xutaoblog.com/post4/20100122306.html)
