It occurred somewhere in 2012 coinciding during penguin penalty. All of my 12 websites were slapped by G & lost all rankings. Around 8 of them had links built in the spammy way(several bookmarks,directory submissions,spun web2.0). I understand that penguin targetted these kinds of sites and so banning them was just. But what worries me is that I also had 2 clean websites which weren't at all involved in deliberate link building were also penalised. These 2 sites had very genuine engaging content and the visitors themselves had built links to it on their own(organic links). These links came from relevant contexual blog posts, forums, Q&A sites,etc. None of them used spun content nor were there spammy comment links, web2.0, etc. Each of them was exactly editorial links as the big G likes. These links itself brought 100s of referral visitors/day. Not a single link was built by us. Then how did penguin affect them? I reasoned a bit and found the common similarities between my clean & not so clean sites: 1# All 12 were hosted on the same account ip address 2# All were all registered in my same name in whois (note: google analytics was not added to all of them and the clean sites weren't added to webmaster tools) But since I was on a shared hosting, I guess there might have been other people's sites on the same ip address and its unwise for google to ban them logically. So I guess that google tried to mass ban all of my sites based on whois. I doubt if its a typical penguin slap! Now here lies my problem. I now want to re-enter the SEO game but am worried that even the new websites that I build now may be banned by tracking my whois. I dont believe that private whois protects anything from google(all it does is protect domain info from general public and spam bots). Here goes my questions: #Has anybody faced this problem and what would be a viable solution to it? #Now I was thinking to start fresh by getting a different hosting and registering new domains with a different ownership name. But isn't it illegal to buy domains with fake ownership data? I really appreciate your time for reading this and thanks in advance to those who will share their opinion.
