You need a lot more than just a lot of articles and a lot of traffic, too -- you need the right kind of traffic. Learning how to do well-targeted marketing takes work. Writing online is not easy money, but it can be good money if you're willing to put in the work. Having 1,000 articles that no one wants to read won't do a bit of good, nor will having 200 hits a day where no one is interested in your ads or affiliate sales links.
Edited: I see you have three hubs. Keep learning, and keep working at it. It's far too early in the game to expect any appreciable income.
