Does Hosting all your sites on one host affect SERPs? I'm intending to host more than 10 sites on various subjects on one US based host. If I continue to host more sites on the site (some of similar content) will it adversely affect things?
It shouldnt really if they are with the same host but it would be different if you have a couple of thousand sites on the same 'server' - Matt Cutts briefly talks about it on this video. I would "guess" only if you dont inter-link them. I have four sites with the same host and they do fine, different subjects and dont link to each other. Is there a reason why you are sticking with one host?
