Some say it does and some say it doesn't. The only people who know for sure are those who work for Google. To be honest if your not linking them together I don't think it will make too much difference.
Most people say that hosting sites on the same shared IP, affect the page ranks of the site (if you are cross linking on the sites hosted on the same place), but SEO wise, Its no problem at all, as every site owner cannot buy a separate dedicated IP for each his website and google understands that. To confirm I googled on this issue and stumbled on many sites like this. Someone else here might be able to guide you better as I'm not really good in SEO stuff. Regards
I agree. We do have clients who host sites with us on multiple dedicated IPs as well as multiple hosts and swear it helps SEO. But whether that helps SEO is still a mystery.
I agree with what Muzamil says. It would be ridiculously silly if Google penalized people using shared hosting.
Umm...ok. Please provide a link from a Google article that says this. If not, sounds like more false rumors. Even if you can find one, Google's (Matt Cutts) been caught lying several times before so who really knows. I just try to use logic... So considering that MOST sites are hosted on shared hosting, and many hosting accounts for many users exist on a single IP. What's to say another jackass on the same Hostgator server doesn't have a site about "dog training" as well as yourself?
There is no effect on SEO to have multiple websites on one web hosting account. The only issue that is possible occurs when you have many text links interlinking all of your websites (site a linking to site b, and so on) all on the same account (IP).
NO. Not at all. The entire "SEO HOSTING" genre' / myth was fabricated by the hosting industry to sell you value ads like IP addresses, and other useless stuff. If it really made a difference google's db would contain about a dozen or less sites.
