I try to follow the rules of how to write a hub, under the help topic, rule number 15, dealing with hub score. I also submit my work to sites such as Digg, Stumbleupon, blogger.com, etc, and that helps get traffic from outside of hubpages. Hubpages takes note of that and acts accordingly. I also answer questions that are asked, not just of me, but in general. In short participation in the HubPages community is appreciated, and rewarded accordingly. Being new to the community, I study the site constantly to see how to improve. I hope some of this helps.
