HP doesn't pay you for your articles. They give you a publishing platform, and you get royalties depending on how many people look at your article.
You have to have a Google Adsense acct. to monetize your Hubpages. If you don't have one you should keep publishing excellent hubs for a few weeks, and after you've got about a dozen you can apply for an acct., then optimize your Hubpages to start earning.
It takes time to build an audience and get consistent views. It took me almost a year to get my first payout of $50; but now 4 years in I make a consistent income of a few hundred a month, which is a nice passive income. Not everyone makes that, but if you write great hubs, advertise and draw an audience, it can happen. Some make more than me.
