Here's some things that have worked for me:
Start publishing more. If you can't publish a Hub everyday, make sure you publish at least two or three times a week. For now, REALLY concentrate on topics you know will be of interest and which will be picked up by search engines.
Comment on other people's work. In particular, search for Hubs similar to your own interest. This way others might see your name, click on your profile, and be happy they found more hubs on the same subject.
Get active in the forums and ask and answer questions. Don't start getting spammy with anything. But be as active as you can. The more your name is out there, the more attention you will get.
