How important are different class c subnets and ip's

[ilyaelbert]

We're thinking of launching several blogs in our niche and 'building them up' organically, and then linking naturally from them to our sites (very conservatively). I was wondering if we should buy entirely separate hosting for these blogs and how important are separate ip addresses and class c subnets (shown on majestic SEO tools for instance). Is it possible to create a set of authoritative blogs in a niche and have them be a little 'neighborhood' within the same shared hosting provider (obv similiar class c or even same ip).

Very hard, You would need to register the domains with different details for example. the pattern of link networks is very hard to hide.

Having different c-class is not so importatnt, unless a high number of your links come from the same c-class. a c-class has 255 ip addresses, but each ip number can host a infinite number of websites, some small towns may have most of their web sites hosted on athe same ip number let alone c-class, so it is not un-common to have such links.

I would suggest you use the content for all these blogs on your own site, and try to attactt links. Haver a link network is dangerouse

I disagree with Alan Elbert, I ran 5 sites within the same niche (forex) which is silly competitive and we ran allow them on separate c class ISP to help cloak all of our linking and versatility on the web, not to mention soliciting each site as a stand alone company giving you higher revenue capabilities on affiliate partnerships etc

Sounds like you're trying to outsmart Google.

Here's my advice: If you have a legitimate reason for creating independent blogs, then by all means do so, but do it out in the open where everyone, including Google can see it, because Google will see it anyway. They have tools of detecting "administratively related" sites that we can't even comprehend. It goes way beyond ip addresses, class c subnets, Google analytics profiles or whois registration data. if you have a relationship with a group of sites, chances are they will figure it out algorithmically.

As an example, the Theme Forrest folks do a great job of this with their collection of websites (try the drop-down navigation in the header to see the relationships) But aside from navigation, there is not a lot of inter-linking between these sites to my knowledge.

It's actually pretty common to run a number of sites under the same company. Danny Sullivan runs Search Engine Land and Marketing Land, and has a number of other sites. These all link to each other naturally.

But be careful. If you're doing this solely for SEO benefits, the temptation to optimize your links and overdo it may be too great, and you may end up in a place you didn't intend. If, on the other hand, the different sites can all stand alone on their own merit, this may be a great idea.

Best of luck!
