Does anyone know if Google checks your whois? Maybe for linking two sites that you own? Maybe for checking to see what other kinds of sites you own?
I am sure they may use a little of that information in certain cases, but I doubt it makes much of a big deal in terms of general rankings. But they may check whois versus some sort of blacklist they have to keep certain specific people out of the search engine, maybe
I would assume if they suspect something is wrong , they have many tools to see if one is not obeying there tos
Google is a registrar that doesn't use it to sell domains. It does give them the ability to check whois - and if you read their patent, it specifically states they can use the information as signals to flag sites with common ownership.
If they suspect a site is whet they consider to be unfair tactics (loads of sites put up to inflate site rank) then yes.
Oh, i made an error. You are right Google checks for hosting IP to find out sites which are hosted on same IP and linking to each other.
If there is suspision,they will dig deep into your site with different diagnostic tools,and i guarantee you they will find any incriminating evidence or tos violations.I say this all the time you might be able to fool google for a bit but google has billions of dollars that will catch on.
Well, Lets say, Maybe they check your IP and stuff automatically just like a crawling procedure or something not to check what sites you have and what are you doing in your life... etc. Google not the FBI!
google checks and knows everything google is big brother but why do you ask? you have one whitehat and one blackhat site and you are wondering if they will nail the whitehat too?
I beleive they keep a track on such information, but it's not necessary an important factor and the truth is: NO body knows any thing for sure unless your working for them and properly in the internal ranking team
