Oops, TwO1FouR beat me to the answer. Yes, if you want Amazon products in your hubs, you have to add the Amazon capsule.
Just in case you need it, here's the help section on how to do it step by step.
You have to add an amazon capsule to your hub. They don't appear automatically as google ads do. Just click on edit, to the right there is capsules you can add.
Click on amazon and there you go!
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.
