The first thing is making them interesting and unique - you want your Hub to be noticed on the web, but not be in the 10th page of search-engine's. To do this, you'll need to check your keywords, to see if they're under-searched, or over-searched. You're looking for about 5,000-50,000 views per month.
Secondly, you want a differentiation of websites to connect your Hubs to - using social-networking sites, such as Facebook and Twitter are good. Using Blogger, Digg, Reddit, Delicious and StumbleUpon are also good for traffic.
Using TraffUp will get your views up, but for each view you get you will lose points on your account - you can top up by looking at other links, or purchasing them.
There is also IMAutomator which automatically puts your Hubs out to the public - without making you do all the linking!
Thirdly, you can always edit your Hubs to keep them updated. Once you get better at writing it's best to check your old blogs and improve them, to a better standard.
Fourth, engage in all communities. Go on Hubpage forums, questions and "hop" hubs, giving good feedback. You'll begin getting followers and more views once you engage more in the Hubpages community.
Getting more developed in other communities is great too! Make sure to get friends and followers on social-sites and back-link websites: such as Reddit, etc. Once you're known in all them fields, you can expect your Hub views to go up dramatically. As your Hub's get older, they will get more views naturally too!
Hope this helps.
