How many hubs does it take to make a consistant monthly income on hubpages?

There is no set number. It's going to vary with the topics you pick, the quality of your content, and your promotional efforts.

I have a feeling it is not so much the quantity but the quality. If you have 3 super popular hubs it's going to be better then 100 hubs no one cares about.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
