You need to analyze, experiment, study the logic from various of things.
1. human emotional - why should they buy your item. price(study your competitor price), they want it(only run ads for user that interest on your product), they afford it(study the country, study the country purchasing power level)
2. credibility - your website, design, logo, name, refund policies, and the most important part is "review", user got 101% confident if they see +positive review about your product, even though the reviews are fake.
logic, logic, apply the logic on various of aspects
our universe have their own law.. we called it law of universe.. or physic.
that similar with 'business'. you need to follow the 'business' law, logic through various of aspect. A, B,C,D,E ... 1 + 1 = 2
if your website can't generate any sale. I believe something is missing, you dint follow the business logic/law enough
