Joining bloggers community can help? Those are the worst because people there will click your ad and expect you to do the same for them.
How many visitors does your site get daily ? 100. 200. 1000 ? You need to see large traffic for there to be any possibilty to earn from clicks what is your site called? whats it about....do you update it regularly? are the ads in a good place or stuck at the bottom of a page that no one will ever see ? I could ask many questions but really cant help you unless you at least say what your site is called and what you have been doing to help promote it, I mean it's unlikely that visitors just appear isnt it.
