Redirecting web pages using 301

If you need to change the address of a page that appears in Google's search engine results, you'll need to use a server-side 301 redirect. The 301 status indicates that the page has permanently moved to a new location. When Google (or any other search engine) sees a 301 redirect it knows that the page has changed location and will carry any link weighting from the original page to the new URL.
