I am moving a 3 years old PR5 site to another domain.. There are about 20,000 pages. I do not want the new site (with new domain) to be considered as a duplicate of the old one. What should I do? How should I move all the files to a new domain so it will not be penalized by google?
Redirecting entire sites with 301 The 301 directive is quite powerful. You can redirect not just single files but entire sites, for example when changing domain names e.g. redirect 301 / http://www.you.com/ The first "/" indicates that everything from the top level of the site down should be redirected. As long as you are using the same paths and filenames, then this option is a very simple way to perform site redirection in the situation where you have only changed your domain name. If the site redirection doesn't work for you, check to ensure you have the trailing "/" on the destination URL.
