ip black seo blog

I got probably a stupid doubt, but anyway....imagine I own various websites concerning different bizs, and I wanna set up a black seo blog in my own language (as would be the first one online)....I would use the same ip, the same intrnert connection of the other websites....do I risk that google will consider all my websites as not reliable and perhaps spammy?

Some people might disagree but I wouldn't do it just to be safe. For example, I've heard multiple accounts of people who had the word "spam" in a domain name and then quickly got penalized - you wouldn't them taking a closer look at the other stuff on that IP. Best not to risk sullying your money making stuff.

I dont know the exact answer but one thing that Google could consider is that since most of the websites are on shared hosting which have a single ip accross multiple accounts. So if Google starts penalizing on basis of ip address than it will effect all the websites on the ip regardless if they belong to the same person or not.

In general it's best to keep shady things far from "home" but, as mentioned Google can't penalize you because for sharing an IP. So long as your not backlinking to your sites and establishing a clear connection they can't assume it's you and blacklist otherwise half the domains on the internet would be tanked.

*SIDE* Do a reverse whois on Google.com they have porn sites on their ip and some other very shady sites.

--> Make sure whois is set to private.
