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

Backlinks from the Same Domain (But Different Pages)
Wayyy back when (in the days of yore) Mr Cutts spelled out in a video that page rank is distributed equally between the external links on the page. If there are two links on a page, each gets passed 50% of the available page rank etc. (Perhaps an oversimplification but bear with me). As a result of this, the company I worked for at the time (this was the dark ages when sidebar homepage links were in vogue) decreed that we would only ever approach a site about a link for a client once, as additional links had little extra SEO Value. Now you could argue that if there are 5 external links, each acquiring 20% of the power, and your site has 2 of those, you are getting 40% of the power, but lets forget the basic math for a minute. I have scoured the web and Mr Cutts' videos and I cannot find the answer to my question: If my site (Site A) has a backlink from SiteB Page 1, and a backlink from SiteB page 2 - does this count as two separate links in the eyes of Google? If the SAME site links out to my site, linking to different pages in different posts, does this give me more SEO benefit? Thanks for your time!

Is there any importance of email signature links from SEO perspective?
We see website links in email signatures. As recently Google has changed its inbox format showing social email (Google+) separately. Is there any importance of email signature links from SEO perspective?

What's more important page authority Vs domain authority?
Hello everyone, I am fairly new to SEO so I'm still trying to get my head round everything, I am currently looking into some back links .. well looking at competitor's back links to copy. I was just wondering what's more important page authority or domain authority? So for example if a page has a page authority of 50 and a domain authority of 10 is that better than if a page have page authority 10 and a domain authority of 50. Thanks so much in advance!

How good is a backlink that's in the footer
Hello, The strongest site in our industry (according to domain authority and excluding wikipedia) said that they would put a sitewide link to us in their footer. We're good friends with them. It would be right next to the copyright. Our site is nlpca (dot) com The partner site is nlpu (dot) com The link will say something like "More NLP Training" with the "NLP" as the link. We're targeting the keyword "NLP" How much will this move us up for the keyword "NLP"? Right now we're on the 3rd page for that term. I also want to make sure that it's a white hat move. Thanks!

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?

What's the difference between follow and nofollow links?
I understand this may be a really dumb question and from my understanding there is a piece of code in some url's that tell search engines not to follow that link. I am interested in finding out what the purpose of nofollow links are and how they apply to search rankings. Thanks for the help
