Your USP is your Unique Selling Proposition.

This is the identity that you create that sets you apart from your competitors in your marketplace.  This is the answer to the question in your customer's minds "why should I do business here?".

One thing that you have to remember though, as you develop your USP, is that you need to make sure that your USP addresses a concern that actually exists in your marketplace.

If your USP boasts something about your business that you think is important to you but none of your customers find important, then you have missed the mark.  If you have a Pizza shop and you are bragging about how fast you can deliver the pizzas but most of your customers are walk-in customers and they actually come there because of the taste of your pizza, then you have missed the mark.  You are promoting a feature of your business that is not relevant to your customers.

As you set up your USP, make sure that you not only identify and address important features or benefits, make sure that they are the features and benefits that your marketplace is actually looking for.
