I have a java programming tutorial blog http://java9s.com Organic SEO and ranks in page 1 for spring programming related keyword. I have more than 10K unique visitors/ month. I am using only adsens now. What are the other ways I can monetize my blog? I find many ads in javaranch and stackoverflow..... where can i get ads similar to that? What else I can to with the traffic I get from the blog?
