I want to build an authority site/blog but just a little confused as to how big i can grow it. Ie: A site about fitness and health, then you add beauty, and fashion, grooming. (Content being good quality) Can you build a site like this or would it be considered spam in google's eyes? (getting links from fitness, health, beauty, fashion sites) Or is it okay if the fitness links are going to the fitness categories only, health links to health,... But obviously some most links would point to homepage. YellowPages gets links from anywhere and everywhere and they rank at the top for everything. (I know its a huge authority directory but it had to start from nothing at one point) Any thoughts or advise?
