The site's home page offers an elegant and simple way for customers to see if they are in a zip code that Kozmo serves. Customers enter their zip codes and then can proceed to a page where they can shop for available items. Another positive aspect of the feature is that it appears right away in the customer experience. Some other delivery sites don't ask for the zip code until much later in the process, forcing users to go through numerous pages before finding out that they can't shop on the site. Kozmo's simple design requires minimal effort from customers and provides Kozmo with all the information it needs.
Customers find out right away if they can shop.
Such simplicity makes for a better customer experience and a more successful site. We still find it useful to display and discuss these features, though, since our aim is to learn from the good or bad design of the feature, regardless of when it was live on the site. In ranking a site, we use a specific methodology . The methodology alone should serve as a great set of guidelines for any e-commerce architect. When it comes to providing the best online experience for your customers, there's no place to go to learn from what others have done.
