We are currently in the process of launching a new website in my non-profit organisation; our old web site that has been around since the end of the 90's will be replaced by a Squarespace site.
Now, our current site ranks pretty high on Google when searching for terms that we would like to be associated with. When we make the change, we will keep the same domain name but the pages will be hosted with Squarespace instead of our old web host.
After the transfer, what will most likely happen to our Google ranking? Are we going to have to start from the bottom again or will some reputation carry over to our new site because the domain name still is the same?
