Customer Centric Web Site Design Uses the USP
Good web site design incorporates the USP to answer the question -
"What's in it for the customer" - the customer only cares about the
benefits resulting from buying your product rather than your
competitors. They don't care about you or your business. It's up to
you to give the customer a compelling reason to buy from you. You
need a crisp, powerful statement that answers your customers'
implicit questions and engages their imagination and emotion.
Your USP has to be a strong, concise summary of your product that
tells your customer why you are the best alternative for them. The
purpose of the web site design is definitely to move product. It is
brief - two or three sentences at most - but it isn't an advertising
slogan.
The USP is all about the customer not at all about you or your
business - don't tell them what you can do - tell them what you can
do for them. So ask yourself what is so unique about you and your
product? What is it that you do that nobody else can do? Sit down and
work it out - it is a very valuable exercise.
Advertising should grab attention by repeating one single message over
and over, but superlatives like the best, fastest and so on won't be
accepted by customers because they will see this as hype!
