"Scientific Advertising" by Claude Hopkins. It's old and in
the public domain, and was written before the term USP
was coined in the 1940s by Rosser Reeves, but it deals
with the fundamentals of how to look for and develop a
competitive advantage in marketing.

Another good free resource is the "10 Commandments of Power Positioning" by Michel Fortin. I read this 5 years ago and still refer to it on occasion. You can google it up...it covers how to make your product/service unique.

There are so many great resources out there for defining your USP. John Carlton definitely has some of the best. As an Offline Consultant, I also ask this question of my clients and help them answer it with some of these questions:

1. What are the benefits of your business?
2. Who is your target audience/market?
3. How do you solve the problem your target audience has?
4. What makes your solution more unique than the next guys?
5. Why would I choose you over the next guy?

Then we break down their business into niches and repeat the process. I hope this helps!

Have a great day!

Here's the best article I've seen on the subject:

Vin gave me the definition that works best for me...

"What do you have that no one else has."

Simplified, perhaps... and I definitely encourage you to check out the resources cited in this thread...

But when I think about USPs that's the line that comes to me.
