I have about 10 sites i'm about to launch. All are seperate from each other and i may do some linking accross them. However I'm not sure wheter i should get a seperate IP address for each domain. Does anybody have some insight? I've heard a lot of different things. Cheers, Roflux
Well too much interlinking between website hosted on the same IP would not be advisable. I actually cannot quantify "too much" for you. You could however interlink if you think that the respective link is going to add any value to the user experience. Mostly Google considers too many links from the same IP to be spammy and may discount them. Just to be on the safer side I would recommend unique IPs if that is not gonna cost you much more than what you are already paying. Play safe.
So if 10 websites are too much what would you say is the recommended amount of websites you should put on a shared hosting account like lets say Hostgator. The reason I am asking this is because I plan on Adding an unlimited amount of domains to my hosting,is that a problem. Should I just have a set amount per hosting account,or is this totally something different.
If you're concerned about cross-linking it might be worth looking for a host that provides multiple class C IP addresses - hostgator themselves do provide such a service - http://www.seohosting.com/
say one person was to have their own IP for each site and the other to have all on the same ip with no interlinking, would there be any difference in terms of SERPs?
I would weigh the actual cost before deciding. Different class C IP's are best if you don't mind paying.
It's not unusual for plenty of websites all with different owners to be hosted on one IP. So in that respect Google cannot conclusively associate the sites as being owned by one person. However if the domains are all registered by the same person then that is a definative association that I would expect Google would use to filter out the 'interlinks'. So assuming the domains are registered under different names or use a domain proxy. You still have to be careful how you go about interlinking. If you simply do lots of reciprocals then I think Google would catch on quite quick and filter them or devalue them. If you do 3 way, i.e: Site A links to Site B which links to Site C which links back to Site A You might get away with some value, but then at the same time I've heard reports that that doesn't work any more. When interlinking the longer the chains are, the less likely they'll be detected. So perhaps chains of 5 or more? But then again - 10 sites? not exactly a huge number, unless you're in a low competition niche you may as well get links some other way.
Bruce Clay observed that although only 3% of web sites are on dedicated IP's, well over 90% of the top-50 results in the search engines are sites having dedicated IP numbers. They confirmed this by moving a site from a shared IP to a dedicated IP and noticed "significant ranking increases." So yeah, if you can get dedicated IP's (even on a shared server) it would be in your best interest.
Completely agree with GotWebHost, dedicated is the way forward if you mean business. It will prove beneficial to you over time, if not straight away. In our experience will clients, this has helped big time. Regards, EIMG
That's an interesting piece of info there, you made me go search for the source... http://www.bruceclay.com/blog/archives/2007/03/which_is_better.html
Having all your sites on a single server and same IP address is ok. But do not cross-link!!! Google will bust you ASAP for "Sub-Net CrossLinking" When we have a good performing site and the keywords are getting very competitive, then we move it to it's own IP address. And not on the old server but a new hosting environment.
