So let's say for example I'm trying to build a niche authority review site where I will review many products and each product and according keywords will have it's own page which I will try to rank. Ok so if I'm using a 3 tier backlinking strategy to rank these pages how important is it for me to build backlinks to the home page instead of just the inner page ? And if It is important how should I do it? Do I do another whole 3 tier pyramid just for the homepage also ? Or do I just include 2 backlinks in my tier 1 articles , one pointing to the home page and one pointing to the inner page ? Or does this really matter ?
