SEO and Web Hosting

A month or so ago HostGator bought some banner advertising on the v7n forums. Not for, but for their SEO hosting division, aptly named

A few people have asked, what does SEO have to do with hosting?

We’ve known for several years now that Google has a patent which filters and devalues inter-IP links.

Quoting Google’s patent:

Re-ranking component 122 begins by identifying the documents in the initial set that have a hyperlink to document x. (Act 301). The set of documents that have such hyperlinks are denoted as B(y). Documents from the same host as document x tend to be similar to document x but often do not provide significant new information to the user. Accordingly, re-ranking component 124 removes documents from B(y) that have the same host as document x. (Act 302). More specifically, let IP3(x) denote the first three octets of the IP (Internet Protocol) address of document x (i.e., the IP subnet). If IP3(x)=IP3(y), document y is removed from B(y).

On occasion, multiple different hosts may be similar enough to one another to be considered the same host for purposes of Acts 301 and 302. For example, one host may be a “mirror” site for a different primary host and thus contain the same documents as the primary host. Additionally, a host site may be affiliated with another site, and thus contain the same or nearly the same documents. Similar or affiliated hosts may be determined through a manual search or by an automated web search that compares the contents at different hosts. Documents from such similar or affiliated hosts may be removed by re-ranking component 124 from B(y) in Act 302.

But if you’re not linking to your own sites from your own sites, why worry about inter-IP link devaluation? You don’t need to. But why are you not linking to your own sites? If you have the link popularity, use it.

We here at v7n own a hundred or so sites, and for the most part they do not participate in inter-linking schemes. Why? Because they are on different topics. Health, finance, travel, etc. Inter-linking those sites would not create much in the way of link popularity, but we still host them each on different IP ranges. The reason for this is, in one word, Google.

Google loves to launch half baked filters and penalties. They do this on the basis of what they know, so it’s in our interest to keep Google’s knowledge to a minimum. At least where it concerns website ownership.

That’s where multiple Class C IP web hosting comes in. It’s the SEO equivalent of not keeping all your eggs in one basket.

It might also be a good idea to keep your domain registration private.

    “Google loves to launch half baked filters and penalties. They do this on the basis of what they know”

    Actually, identifying linking networks through IPs is amazingly effective for catching link spammers who are too lazy to use different IPs. You can dig up a good percentage of the real estate link networks, for example, through IP tracking. In some cases you got hundreds of real estate agents on the same IP block, all linking to each other.

    But I’ll go out on the limb and say different IPs won’t matter unless you’re going to keep your whois private. Google can’t verify website ownership with IP alone, obviously due to cases where you have different webmasters hosted on the same IP via virtual hosting. To identify any spammy links between those sites, Google has to dig into whois information.

    OK. I understand. Guess I’m paranoid!

    We all know Google got into the Registrar biz a couple of years ago.

    Now, how private is “private” registration? Does Google have access regardless of the privacy setting simply because they are a registrar as well?

    That is the way I do it. I have my domain name private so as to avoid spam and or id theft. I also have a hosting reseller account using cpanel and WHM. I just need to advertise and get the word out

    There are other ways to get good links, like article marketing with a resource box. I use article marketing almost exclusively. You can submit the articles yourself, or you can use software to make it much faster. I have been using Artemis Pro this year, and it’s made the process go a lot faster. If you have speed, you can work up a lot of links in a very short time.

    For John Scott,

    I had Mel Nelson do some work for me then referred a friend to him. After Mel did some smalls jobs for him he decided to have Mel do a large project and advanced Mel $10,000. Mel then disappeared.
    Do you have any ideas on how to best deal with retrieving this money?

    Sorry to hear about your trouble. Maybe do a charge back on your credit card?

    If you do interlink the websites, and they use seperate C class hosting servers, then make sure you thoroughly outline (read: plan) your linking tactic before arbitrarily going through and linking. In general, I think a series linking pattern is least likely to attract attention. As soon as you close the hub, you are signalling a closed group, which is much easier to detect.

    This makes a lot sense. I recently use this inter-linking with different hosts strategy to make a PR3 blog from scratch within 2 months. Link exchange is just out of date, this inter-linking plus blog comments are most effective PR boost methods at the moment.

    I’m not sure this is a penalty or perhaps only a devaluing of the link. There’s no question that interlinks are less valuable and while there’s potential for spamming here at least some interlinking is a natural process and serves a practical purpose, especially among sites of the same genre. I doubt it would be worth it to have separate hosts for this purpose though as this is probably not a cost effective solution.
