Its headline tells a reader who this ad is targeting, what's the cause of the problem, picture of the product, how the product works, the benefit and an incentive (20% discount) for taking action.
However, it fails to address the more important issues:
1. Is it necessary to take this for constipation? Why?
2. What happens if a customer choose to ignore the problem?
3. Why should a prospect choose this product over its competitors? More importantly, why should a prospect choose this product over doing nothing?
4. Why should a reader even bother to read this ad in the first place?
Now, if you are selling this product, what would you do to increase the response rate of this ad by 500%?
