How do I increase visitors on my blogs?

I have other Blogger blogs, and this is the latest one that I created. I am thinking of deleting my other blogs since they are not doing very well in terms of revenues on advertisements in adsense. But on the other hand, I have already posted some things there that are for me are valuable information. I am still trying to figure out how am I going to make more out of these sites. My other blogs, by the way are: Lutuing pilipino.com ;Bisnes Online ; if anybody out there is reading these blogs, kindly comment on my blogs on how am I going to increase the visitors of these blogs.
