Hi folks, I just wanted to see if I can get some advice. I wanted to focus on a building one large blog in the area of music/equipment. I have a personal blog that is a pr 3 (not making any money). Should I started fresh with a new domain (so I can something registher a catchier, better name) or should I just build the pr3 one that I have. Would a pr3 help a lot more in rankings?
