what is the best products to sell from amazon?

hey guys!
i stared with amazon few months now and i sell only some bestselling ebooks, but i didn't earned more that $1 per sell.
I'm thinking to change the game and sell something with high payment because as i've seen i can get best traffic from google without spending a dime!
that's why i'm looking now which products are good to sell ?
