I have 5 domains that Im targeting the same keywords with. The domains are all hosted on the same server. Does it hurt my SEO efforts having them all on the same server using the same IP address? Should I be hosting the sites on different servers or does it not make a difference?
Having them hosted on different i.p.s would certainly help but it wouldn't make much of a difference either. If you want to rank each of them and want to link them too, make sure you do it right. Too much linking to one of the 5 and less to the others would make your rankings unstable. Randomize the way you interlink them and don't follow any related linkbuilding pattern.
