Not makining anything with Amazon

So I created a amazon affiliate store on WordPress with woocommerce, and i promote the product with pinterest . I found this idea from some people on here with great success but I have not been able to make a single sale. I have also tried using other forms of social media but still no success. I am not sure if maybe affiliate marketing is just something I can't do because I have also tried other affiliate marketing places with $0.00 results.

Hm how long has it been since you started out? Sometimes it takes a while but hard work pays off

Was the site content unique ?
Is the site indexed and showing in search engines ?
How long ago did you build the site ?
