We currently have a site hosted on a 'local' ISP (in quotes b/c I don't know if they are a reseller), but we are not impressed with their resources. We are thinking about moving to a bigger service (godaddy), but there's concern we may loose our Search Engine results - which we are very happy with.

So... if nothing else changed other than the ISP host, do we need to worry about loosing rank in Search engines?
