Tomorrow I will being moving a client off of Go Daddy’s Web Designer account, which is quite possibly the worst thing ever, and moving them to a Go Daddy Hosting Account. To do so I have to change the domain name of the Web Designer account and then create a new account. The current webpage is number 1 or 2 in google and bing search engine results, probably because its a town. Is there a risk that by deleting the current account and moving the domain name to a knew one that the new webpage will be ranked lower? And what should I do about it, if there is?
Like @TheDoc suggested in another post, just use a redirect (301). You should not have duplicate content on two separate domains as Google may find that suspicious according to one of their latest algorithm updates.
