A unique selling proposition defines your position in the marketplace and lets you stand apart from competitors.
One simple strategy for identifying a unique selling position is to fill gaps left by competitors. You can use the reviews etc to find these gaps. Such as 3-4 star reviews, which usually identify something lacking.
Points in defining your unique selling proposition:
- Product/service description
- What are you not going to do
- What will be unique
- Proof your solutions work
- Pricing strategy
