You have posted this question in the wrong forum, you should ask this question in the general marketing forum.
I agree, this isn't the appropriate section for your question. I do know someone who does specialize in promoting blogs, so hit me up if you need anything.
If you do not have visitors, they do not mean anything.. if you do.. there are many ways to monetize them.. selling products, placing ads on them..
Yea, Just use everything you can to get traffic.. Then moneytize them.. using Adsence or Bidvertiser or other things like that
