Virtual vs. Dedicated IP's - GoFuckYourself.com

Interesting read from Matt Cutts' Blog

I hear that there was recently a discussion on a NANOG (North American Network Operators Group) email list about virtual hosting vs. dedicated IP addresses. They were commenting on the misconception that having multiple sites hosted on the same IP address will in some way affect the PageRanks of those sites. There is no PageRank difference whatsoever between these two cases (virtual hosting vs. a dedicated IP). Someone on the email discussion already dug out this Slashdot interview from mid-2003 with Craig Silverstein, Google?s Director of Technology. I refer to question 5, in which someone asked

Quote:

Why in this day and age does google continue to penalize sites that are virtual hosted? With ip addresses becoming harder to get/justify every day why does google discount the relevance of links that don?t come from a unique ip address. Please don?t just deny it, I think the Internet community deserves an explanation.

Craig?s reply was as follows:

I can?t just deny it? What are my other choices?

Actually, Google handles virtually hosted domains and their links just the same as domains on unique IP addresses. If your ISP does virtual hosting correctly, you?ll never see a difference between the two cases. We do see a small percentage of ISPs every month that misconfigure their virtual hosting, which might account for this persistent misperception?thanks for giving me the chance to dispel a myth!

I?m happy to affirm that this statement which was true in 2003 is still true now. Links to virtually hosted domains are treated the same as links to domains on dedicated IP addresses.

That may very well be true but it may not be. Many who optimize for search engines not only get on their own IPs but ask for them to be on different blocks. What is true is that search engines penalize for sites that they see as spam. It seems to me that if all of your sites are on a shared IP with the same registrant information it would be quite easy to connect the dots and blacklist sites of little value with duplicative content.

I believe most that play the search engines agree that the obscurity certainly can't hurt, especially if you are publishing dozens, hundreds or thousands of domain names.

We are very generous with IPs!

Oh, i wasnt trying to speak that as the gospel or anything... shit... I think i'm up around 200 IP's for personal projects right now.

Even if they are treated the same, it still makes a huge difference, Brad is right and Matt hides an important fact in his statement: If multiple sites share an IP and are heavily linked, the detection of a link network, which could lead to penalties, is alot easier...they wouldn't even need to check the whois.

Speaking of registrant information, google filed a patent that includes some sort of whois routine...

Google is good ? Their army of lawyers is just to protect them from the evil ? They scare me much more than microsoft ever did !
