Read the Learning Center. I know when I say this, many people probably thinks it's not but a lame FAQ with very little information, but I'm telling you:
If you want to do well on HubPages -- make money, get traffic and all that... Read the stuff in the Learning Center. I can understand why a new user would naturally meander over there from the get go, I mean I've joined PLENTY of sites and never bothered to read the "help" sections, but SERIOUSLY the Learning Center has EVERYTHING you need to know about making great hubs and how to write hubs that make more money.
This is the number one question I get on HubPages - How do I succeed here and 100% of the time I include "The Learning Center" as the focal point of my answer.
I hope this was helpful!
