All are here for making money, but only a few are planning to deserve them. Don't just simply make any guesses and blindly follow it. Everything should be according to the planning, one wrong move and you're gone.
I am not here to teach you what's wrong and what's right, but I can suggest you something valuable which has helped me in the past and I believe it will help you as well. Signup for Google Webmaster Tools, pick up a niche and search for the keywords to get the maximum earning value. For example, insurance niche will get you a good amount of money, if worked properly. You will surely get the hits if SEO and marketing are done in an apt manner. This way you can earn a lot of money with a site.
I hope, I helped you. Good luck with your site.
