A ‘value proposition’ is the thing that a customer actually wants to buy from you. Your product might be just a way to get the thing they really want.
Your value proposition will be different for each type of customer. Different types of customers have different motivations.
There are only five main reasons why people don’t buy: no need, no desire, no money, no trust, no rush.
Identifying which of these is the reason people are not buying your product will show you where you need to focus your marketing activity.
