Considering that the original domain had been indexed by Google and remains on their database even after the new domain had been registered and all content from original site moved, will the new domain be considered as having duplicate content of the original domain? Thanks in advance.
I don't know exactly so you should wait for more replys after this, but how it seams logical to me is to make a 301 redirect with the old domain to the new one.Just saying.Maybe someone esle could share theyr experience.
I thought of that too but I was just worried about indexed pages that still remain from the old domain. Hence, the new domain's content may be considered as duplicate.
