Is ezine article publishing given any credit in deciding hubber scores of hub pages?

Maybe indirectly, by increasing your traffic. I don't think that there is any direct benefit.

Possibly more traffic = more hub score. Also, longer hubs have more score as compared to shorter one. I never did any ezine.So, really don't know the effects.

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.
