How Does Google connect Owners of Several Sites?

[joemas99]

let's say I own 20 sites, all non duplicate content and Google sees that some of them has linked to sites that they consider a "farm" or other violation. So they give penalties to those sites. What happens with the other sites and how can I keep sites the most independent?

For ex: These are my questions...

Will google follow no follow links to see that they are connected to the good sites and penalize them?

If they are all part of google anaylitics with good and bad sites, will google attack them all?

Will google look at the owner of all the sites and connect them that way/

I need to know the extent Google connect site owners for penalizing. please only answer with knowledge, and if you can supply specific links, that would be great too, thanks.

I was afraid I needed  dedicated ips, had that before then switched, we switch back.

It may be impossible to have separate names and addresses, can you let let know what source I can go to to get the latest on this. Things are too critical to risk based on any opinion, including mine. Thanks for responding again.

Separate IP's, Content, Phone Numbers, Addresses. I wouldn't cross-link any of them and aim for getting dedicated links for each domain from different IP blocks.

thanks, even if the links are no follow and don't pass rank. ?

For starters

-To keep them Independent you want to host them on separate ip's

-If All sites link to each other you will be seen as a network by google - ie link wheel , link exchange networks etc
