How come only 2 people have signed up to hub via my referral link?

It sounds like you aren't targeting your HubPages referral link to people who genuinely want to join the site and write. Referrals won't earn you anything unless you sign up people who then make a good quantity of really good Hubs. Out of all my sign-ups, I've got a few good Hub authors in there, and I earn over $100 a month just from them.

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.
