There has to be something wrong with your ad. Did you start with 5 dollars per day? Its best to grow slow and scale up, and not going full force from start. Also, ad test different audiences and see which brings you lowest conversion. Test split identical ads where you just change the image, same copy and see what facebook prefers. Then attach to that image, and test again different ads with everything identical except the headline. Once you found The Ad, search for the audience. Use demographics insight of the last ads and see what gender/age converted and aim for them Ps. Always use behavior "engaged shopper" if you want to aim for people with compulsive buyer behavior
