I have a serious helath related site. Decided to purchase 20 domains names that i plan to use as blogs with 10 articles max each to improve my main sites SEO. Is this way still effective? I have heard that if you do not have a reseller hosting account google can easily follow the footprints and find out that your main site is related to these 20 sites. Do i need a different IP for every site? What is the safest way to do this? Also i am using a "baby hostgator plan" which allows you only have sub-domains hosted. Would this baby plan work or i need a reseller account to avoid sandbox?
