[User Interface Engineering] The $300 Million Button explica com un simple canvi en el formulari de compra d'una tenda ha augmentat les vendes en 300 milions de dòlars. El truc, ben simple: no obligar als usuaris a registrar-se per a fer la compra.
The form was simple. The fields were Email Address and Password. The buttons were Login and Register. The link was Forgot Password. It was the login form for the site. It's a form users encounter all the time. How could they have problems with it?
The $300,000,000 Fix
The designers fixed the problem simply. They took away the Register button. In its place, they put a Continue button with a simple message: "You do not need to create an account to make purchases on our site. Simply click Continue to proceed to checkout. To make your future purchases even faster, you can create an account during checkout."
The results: The number of customers purchasing went up by 45%. The extra purchases resulted in an extra $15 million the first month. For the first year, the site saw an additional $300,000,000.
