I just changed my business website domain name (and business name, for that matter) from www.divinadesigna.com to www.hilevelsem.com . It was a process, done correctly using 301 redirects in the .htaccess file. If you are thinking of doing the same, please do it carefully as a botched transfer can cause you to lose some if not all of your hard-won search engine rankings and traffic!
According to SearchEngineNews.com (in my humble opinion the best and most reliable source of SEO knowledge and news), it's preferable to NOT change your domain name unless you absolutely HAVE to. Or have the ITCH to, like I did ;)
If it's unavoidable to change your domain name, however, then the way to do it revolves around the proper use of a tool called the 301 redirect. The number 301 identifies a specific 3-digit server header code generated by a Web server when a browser or search engine spider tries to download a Web page. The 301 code says the page has been permanently moved to another location. At this point, browsers and spiders then know to "redirect" themselves to the new address. The cool thing about 301 redirects is they can be used to move individual pages, directories or even entire sites. These directions are all specified in a document that resides on your server; it's called your .htaccess file (spoken "dot ht access file). If you don't know what that is or how to write the 301 redirects properly for your site hosting configuration (UNIX, Windows Server, etc.), and you want to "do it yourself", I recommend becoming a member of Planet Ocean's Search Engine News (click the banner below), and then browsing to this article once you are a member: http://www.searchenginenews.com/se-news/content/how-to-change-your-domain-name-without-losing-your-web-sites-rankings2
