I'm not quite understanding what you are asking. You want to run 15 WordPress Blogs with AdSense on them? Is this what you're asking? All you do is install the WP blogs on some hosting with a domain, sign up for adsense, and start making adsense ads.
This I have already done but all are new blog. I will post every blog in 48 hr. how adsence will help me in earning. I have adsence acount but that is no getting good sum.
Its a bit confusing.. you want to create blog for adsense or want to create blogs with adsense on it?
you are not getting money, because there is no traffic in your blogs, or ads are in the places where nobody see them
Good advice from some good brains. one more qustion on my mind. If i continue my one blog- in one particular subject then what are the way to Accumulate all the traffic in my blog. Dose it depend on the use of good key words? if yes- then should I use all possible k-word in different categories of one particular subject in good number of post or any other methods of formulae are there? e.g. a Hosting blog should use all kind of Hosting related kwords in different categories so the hosting related traffic caught my blog.
