.blogspot.com IP duplication

[MatthewHamilton]

Would Google give a given site credit for being linked to multiple .blogpost.com blog's, despite them emanating from one IP address?

I think if the content linked to has a quality and uniqueness to it and other sites that are linking to it from the same IP/ site have relevant subject matter and content, it should not be that much different from external sites outside *.blogspot.com. Providing is white hat of course, the same ranking rules apply is my guess. You see a lot of well visited blogspot sites, for some you think why they don't host the site on their own dedicated server/s due to how big they are, but maybe they are happy where they are.

shared hosting is generally though of as second best and many believe if a site is to gain serious traffic and value, should be hosted on its own dedicated infrastructure, however, we are talking of sites worth millions here.

thought of I mean!

Are you asking about links FROM many blogspot blogs, rather than links TO them?

Having a separate hostname makes a lot of difference in treating these links as coming from different "websites". The IP address is not that big a deal in this particular case, and I assume that blogspot does use a lot more than one IP address, anyway.

I'd even bet Google's algo has gone one step further. It has an idea when many different blogs have some common ownership or influence, based on the total website footprint, and discounts the value of those links.

I meant links coming FROM .blogspot.com. My question is would each link from such a page count as a vote; or would the single IP address (common to the list of 20 odd inbound links from different .blogspot.com pages to the site I am working on) render them without value?

Would be interested to know if there is common consensus on your thinking re: Google's realization of a varied website footprint....

Thanks for clarifying. then my answer stands as I originally wrote it.

It's the hostname (subdomain) that is most important in defining a separate website in this case - and in other parallel instances, such as wordpress.com, typepad.com etc. There have been many domain names over the years that farmed out various hostnames to different users.

Also note that blogspot blogs do NOT all have the same IP address. I imagine some are sharing an IP address but that alone will not mean that Google treats links from them as coming from "the same site".

By the same token then - I have experienced researching inbounds links to a given site where the majority of high PageRanking inbound links seem to appear from the original site's companies other web properties (yet with different IP addresses for each one - although all IP located in the same, foreign, city) - does Google have any mechanism to realize when a commercial entity attempts to host each of her branches from a different IP address and create the impression through blanket inbound linking of authority, trust, relevance and standing within the sector/industry and then de-rank accordingly? These were sites within the competitive world of travel; each highly ranked (PR 4-6) and not each branch/location of the continent wide company appeared to have her individual site benefit from this IP splitting....

[tedster]

Yes, they do. Whois data is one such mechanism, and statistical analysis of the web's link graph is another.

At the same time, it is common for some enterprises to have several web properties that use different IP addresses. It's not always an attempt at manipulation.

[MatthewHamilton]

But is does seem to be rather an effective strategy at times - from what I have seen...

[tedster]

Yes, Google sometimes does "count" these links from multiple related blogs. They're not illegal or anything. A lot depends on which blogs and which target site we are talking about. If the trust value is high, no problem unless things start to get really spammy.
