I find that by using the "Hub Hopper" and reading and commenting on other people's Hubs brings me new followers. To get followers however, you need to have good articles based on things that people want to read.
I recently wrote a Hub about how I perform my daily Hubtivity. My audience has been growing ever since I made some changes! Here is a link if you are interested: https://hubpages.com/community/So-You-Want-To-Be-A...
Another great tool that I suggest to all new Hubbers is to view the Learning Center. There is so much valuable information there that will answer most of the questions you have about HubPages. Here is that link: http://hubpages.com/@learningcenter
I hope that this helps!
