Amazon says Fail: The link above was not tagged or was not a valid Amazon link. How is the?

I'd check the affiliate settings (assuming you have an amazon affiliate account):My Account->Affiliate SettingsCheck your status for Amazon is 'set' and make sure the affiliate ID ends in '-20'.

Yes, the ID shows correctly. I am thinking that maybe I am looking at Amazon and other one differently. AdSense shows impressions and clicks but the other probably don't show page impressions...could that be it?

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.
