301 Redirect, is not unfamiliar to the person who has done search engine optimization. But for just contact SEO Rookie, may be a strange thing. Simple introduction, 301 redirect is a Web page is permanently transferred from one URL to another URL.

Since 301 redirect is a permanent transfer of a URL to another. So when are we going to need this technology? In fact, when we build a website, we often encounter pages that need to be redirected.　For example, the directory structure of the page changes, the Web page extension changes, the site to change the new domain name. On the surface, a 301 redirect is not a permanent transfer of a URL to a specified place. But for search engines, it has a different meaning. The 301 status code tells the spider that the Web page has been permanently changed to the new URL and will make the spider program do two things that are extremely important:

1, crawl through the new URL of the Web page. The spider program will use the new URL provided by the 301 Redirect to find and crawl through the new page, as you mean. It indexes all the content on the page and includes the new URL in the index library, so all searches with that page will lead the searcher to the new URL, not the old one.

2, the old web page of all the connection value to pass. I think we all know the importance of links to the site, when other pages linked to your Web page, will give your site to pass weight. When the spider program sees 301 relink, it also updates all the link information in the index library, so all the link weights for your page under the old URL are moved to the new URL.
