I believe the main factor is generating traffic through. I haven't concentrated on that. I have associates. We are building. HubPages will help with that, and that will help with HubPages. It is a tremendous amount of work! I believe it will pay off.
Remember, it is what you make it, and this should be a "Hub" in a wheel of your efforts.
