I have a few clients I am setting up local SEO programs for. I was wondering if any had and input of my systrm before I set it in full swing. What I am doing is I purchased a domain and am making a sub domain for each clients local website. I build a seperate site with all local key worded pages and thren im going to backlink em. My major concerne is sub domaina over ranking regular domains in the SERPS. Any one try anything similar?
