It took me about two months to realize I made anything. I am up to about $1.50 after almost 3 months of hubbing and 11 hubs. I was ready to give up seeing as how I didn't think I made a single cent, but eventually I figured out that I had to check my payment history and it was then that I realized I was actually making some money.
By monitoring my google adsense and my google analytics (as well as the hubpage statistics) I was able to quickly determine the extreme importance of backlinking. I am currently reading up on backlinking a bit more, though it seems fairly straight forward and simple (almost a no-brainer). I just don't think I realized the impact just getting a hundred views here and a hundred views there can make.
So far it seems to me that if you politely find a way to work a link to one of your hubs into a content specific message thread in a relatively active forum you can pretty much count on that seed bearing fruit. Of course it helps if that forum is "dofollow."
I'm new at this, but whatever I am doing is working so far. I just have to get better at it. Don't give up!
