Beginning on Hubpages can be overwhelming if you don't break it up into steps. I've been on the site for over a year and am surprised at what I still don't know. I know there are people out there that make a great deal of money every month, I am striving to figure out how they do it.
The first thing you need to do is write, write, write. Write about what you know and what you love. If you need inspiration click on the Hubbers link at the top of the page and look at the top Hubbers on the site. Read their hubs and learn what a GOOD hub looks like. Don't post garbage.
After you have a few hubs posted you need to drive traffic to them. Post your hubs to your Facebook account and Twitter. Then read some hubs about backlinks and join a few sites to try to get readership that way.
Good Luck. It isn't easy and the only formula for being successful is perserverance.
