If I cancel adsense ads, does my hubpages ad program earnings go up?

You've got it all wrong my friend. Your CPM is based on the ads shown on your individual articles. Deleting your Adsense ads will not help you gain more money on Hubpages ad program.

If you have an article in a competitive niche you are going to get paid a higher CPM. However, it's going to be much more difficult to get traffic to these articles because of the competition. To answer your question bluntly, do not delete your adsense ads.

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.
