Does Google Use WHOIS Domain Info?

[hydseo]

In some cases Google seems to devalue the WHOIS domain owner and this results in a simultaneous ranking drop in several sites under the same domain account.

Anyone face this problem?

Don't understand your statement and question...

[breeks]

Google knows how many times you make a bowel movement, so I'm sure they who owns what web site.

It's funny, I thought about this today. It's a very good question. It wouldn't surprise me at all if they have a huge database of whois info and they link it up with sites they consider "bad" and punish those in that database.

Seems like private registration would fix this, or listing your whois info as someone or something else might help.

Google is a registrar. They already have access to all public WHOIS data including historical WHOIS data. I doubt they use it in their real-time algo, but surely they use the data when researching spam reports, manual penalties, reconsideration reports, etc. They don't have access to WHOIS data protected by privately registration.

It is possible to burn through WHOIS privacy in some situations. I'm not sure if Google has to kind of people with the abilities do this kind of thing though. Switching to a WHOIS privacy service could indicate that the site owner has something to hide. These are, after all, the people who brought the web the Animal Farm updates.

My question is: I have to 10 websites with unique content, unique ip address and all websites are hosted in one server.

If one domain effected by panda or penguin is there changes to effect remaining websites in same server?

@hydseo

Nope. Only if google looks at your whois info and says, "You know what? F*** this guy. We don't like one of his sites, so let's punish all of his sites."

As ZydoSEO said...

I think they started to use WHOIS years ago when they try to fight buying expired domains.

hydseo - Is your question somehow related to this one, which you also asked?...

My Web Host Network Lists Spam Domains
http://www.webmasterworld.com/google/4578895.htm [webmasterworld.com]

My website is in host network which contain nearly 20k domains in these domains some have adult, malware and spam sites. Are these site will effect my website ranking?

My guess is that in such cases, if there is common ownership, and Google had reason to review a site for spammy behavior, Google might spot the ownership... particularly if the sites are networked in some way that touches yours.

Your new question...

My question is: I have to 10 websites with unique content, unique ip address and all websites are hosted in one server.

Google's very good at spotting related domains, and they could do so even before they became a registrar. They look for multiple signals that confirm coordinated action. Hosting on the same server might be one set of signals, but I think they'd want others before assuming association. Networking in conjunction with hosting is a strong sign of coordination.

I don't think that sites affected by Panda would be under scrutiny, as Panda isn't about spam... but sites affected by Penguin, with common hosting and enough common link sources, might draw attention.
