First thing you want to do is make sure you have your adsense details are in your account.
Next thing you want to do is back link your sites or other hubs you like and then they can also back link your sites - you can rate each others higher to get on the front page. They call them scoops. Want I try to do is scoop people's hubs that I enjoy and vice versa people who have joined with me tend to do the same. This gives a higher rating and then more traffic as a result. Team effort.
This all gets very time consuming and I notice people have scooped some of mine and I aim to return the favor. You just have to make sure you write a little intro and it a little different not just cut and paste. If it is the same you are duplicating and therefore your google ranking is affected.
I hope this helps and thanks for joing under my ID :)
