I want to host multiple websites each in different Niche and has Reseller Hosting with shared hosting used only by my websites. I will be using SEO to drive traffic to my websites, I want to ask if there would a problem with SEO ranking or Google penalizing my websites for shared IP's but all websites are in different niches. But I would be using same Websites for Link Building like same Link Directories, Article Directories, Social Bookmarking websites etc.
