How important are different class c subnets and ip's
-
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).

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!

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

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

What impact does multiple links from the same c-block have on SEO?
Recently there's been a move made in my company to only allow backlinks from websites on different c-block IP addresses. The most links we have from one c-block is 15. There is a wide variety of other IP addresses linking to our site as well. My question is - do we need to be so restrictive with using websites from the same c-block as long as the neighbourhood is good and we're not linking sites with full identical IPs (matching d-block as well)?

What Makes A 'Natural Link Profile'?

Internal Linking - Post links vs Side Bar Links behaving differently
Hi, I have a question regarding the internal linking behavior. My website is www.hindimeaning.com which is approx 3 years old. I have approx 450 posts. Now i have a widget on right sidebar "Popular posts". A widget below my posts "Related Posts". And a simple html CSS menu above the posts (I removed menu around 6 month before so currently it will not show.) I crawled my site with moz crawler (same are the result from google crawler as well) and it shows menus links as internal links. While sidebar widget "Popular posts" and "Related Posts" are not showing as internal links. If we talk theoretically what i learn till now is "every link on a page behaves as internal link". Then why the widget links are not showing as internal links. Thanks, Mahesh Kumar

How important is the originating country of backlinks?
How important is it that you gain backlinks from websites in the same country you're targeting? Scenario: You have a website targeting users in Japan. How important is it that backlinks to your website are from Japanese websites? Do you need a majority of links from Japanese websites to rank well, or will you do OK with 25% Japanese links and 75% links from other countries? According to Majestic, sites for popular Japanese brands like tsutaya.co.jp and seiyu.co.jp get more links from US sites than from Japanese sites.

How do paid directories like thomasnet.com do so well in the serps? Aren't the Panda updates supposed to be moving us away from this?
With all of the updates/changes to Google's algo, I assumed that paid listings & links like those on thomasnet.com would have less merit. Is this an incorrect assumption?

Quotations about importance of social media and backlinks
Hi all, I'm looking to put together a presentation on SEO and I'm wondering if anyone knows any good quotes that relate to the importance of having content on your site that people want to use and share. I'm looking for something like this: “Today’s marketing success comes from self-publishing Web content that people want to share. It’s not about gimmicks. It’s not about paying an agency to interrupt others.” David Meerman Scott “The New Rules of Marketing and PR” but ideally something that illustrates in terms of numbers how much more traffic and seo benefits a site can expect from having good guides, pdfs and news stories that people want to share. Thanks so much for any helo you can offer. thanks, David

How does Google interpret articles or prepositions in languages where it's attached to the (key)word?
Hi, All! This is for any foreign language SEOs where articles or prepostitions such as "the" "to" "in" or anything else are actually part of the word they are modifying and not a separate word, as in English: How does Google understand those words on-page and in anchor text? If you want to optimize for the word "house", and your content/anchor text says "the house" or "in the house" (again, all one word) - what does Google count that as? Does it count toward "house"? Does it count toward "in the house" only? Does it count toward "house" but not as much as if you had just put "house"? I end up sometimes writing slightly grammatically-off content because I want to optimize for the keyphrase - but is that necessary? Obviously different languages might be different, but you can probably project a little from one to the others. Thanks in advance!
