I use a 'sitebuilder' for my website which now has me a bit restricted in what I want to do. I have found another Host/Sitebuilder that have all the options that I am looking for. I intend to keep the same Domain that I am currently using. My question is: If I change over to a new host/sitebuilder will this have a big effect on my rankings/PR etc? Thank you for your time
if you able to keep the same domain then it will fine. But you need to make the pages in previous order so that it won't show page notfound MSG. It degrade you PR.
