Hi, I have one main site, let's call it  food.com I also have 10 smaller sites, let's call them   mexicanfood.com, indianfood.com, italianfood.com etc food.com is on its own separate dedicated server the 10 smaller sites are all on a shared IP in hostgator I don't want Google to think that I have created the 10 sites for only purpose of creating links to each other. So, would you recommend that all those 10 sites link to each other? or should there be no interlinking within those 10 same IP domains? What about linking from those 10 sites to my main site? How should I structure my own backlinks not to get penalized by Google ?
