Traffic loss is inevitable after a domain name change, but there are techniques that can be used to minimize it.� The most important is to let regular visitors to your site know about the domain name change before hand and they should update their bookmarks if they have them.� The next thing is to use a redirection to the new domain site's name if possible.� Eventually the traffic will go back up, but it will not be until the new domain name is processed by the search engines.
