The shortest definition of USP (Unique Selling Proposition) that I know of is:
“What do you uniquely guarantee?”
USP is THE defining question if you are marketing on the Internet.
20 years ago most businesses could afford to be vague about their USP, especially if they were local. If you owned a shoe store and there were only two other shoe stores in town, then if you sold Nike and the other guy sold Converse then that was enough. You probably didn’t even think of it as a USP. It was just a difference. Any difference would do.
The Internet of today is different. Online, you must be unique in all the world.
