Internet marketing for Health related niche

Hi,

I have 4 health related projects, that i am running for nearly a year, i have not done much works on those - keyword research, link building, article submissions...

There are sales, but not enough to live from this. I would like to put a bit more efforts to make a good profit from those 4 websites, for one i already have 3 years old domain name.

Could you suggest some internet marketing methods that will increase sales in my shops

Kind regards
Kal
