Special Design Considerations for E-Commerce They include learning to incorporate methods for eliciting feedback on the Web site from ecommerce customers and four ways to provide one-click navigation on ecommerce sites to ensure that customers can easily navigate the site and that they can readily return to it.
1. Soliciting Feedback from E-Commerce Web Site Customers There are two standard ways to design what users will experience when they click on the Feedback button:
1. The first way is to launch the user’s email program with the email address of the company’s contact automatically entered into the To: field.
2. The second type of design for garnering feedback from customers using an ecommerce Web site is to take users to a blank message template when they click on Feedback.
2- Easy Navigation for E-Commerce Web Sites Many authors speak of what is known as “intuitive navigation” for ecommerce Web sites. Users need to know how to navigate the site without having to learn a new interface and without having to explore every inch of the Web site before they can find what they want. The standard for this type of navigational approach is called one-click navigation.
There are four ways to design easy, one-click navigation for an ecommerce site: (1) creating a rollover menu (2) building a collection of hierarchical links so that the home page becomes an outline of the key topic headings associated with the Web site (3) placing a site map on the home page and emphasizing the link to it (this would also be placed on every other page on the site) (4) placing a navigational bar on every inside page (usually at the top or on the left side of the page) that repeats the categories used on the entry screen.
Mashups An application programming interface (API) is a set of small programs and protocols used like building blocks for building software applications. When two or more APIs are used together they form a mashup.
