I. Content Issue

When you open your page in a browser,

what do you see? If you've created ausable website, you should see 80-90%what your customer is looking for.However, with most websites (yes, this siteis no exception), usually what yourcustomer is looking for only constitutesbetween 50-60% or less of the mainportion of the page. The rest is ads,confusing navigation, and extraneousgraphics.

Closely related to content is how thatcontent is displayed on the page. While

studies have shown that people are willingto scroll to read through web pages, if they

don't find relevant content quickly, they aremore likely to leave. Keep your pages cleanand simple. Remove elements and see ifyour page needs them, if the page

functions without them take them out.

II. Page Layout Issue

7/7/12

Colors can affect the usability of your

website. Web browsers have standard colorsthat are used for links (blue for links, violetfor visited links, and red for active links).When you use other colors, you run the riskof confusing your customers. Also, colors ofother elements of your page can affect your

readers. For example, color blind customersmight not recognize color coded images.

The version-specific elements of HTML

will automatically exclude some of yourvisitors. The only way to be absolutelyusable is to limit yourself to HTML 1.0.According to Jakob Nielsen, "it will be ayear before the majority of users willeven be able to access your fancy use

of new technology." The best solutionis to avoid beta-level technology untilit has been in use for at least one year.

IV. HTML Issue


9/43

7/7/12

Access to the Internet may be getting faster,

but that doesn't mean that Web pagesshould get bigger. In fact, Web usabilitystudies continue to show that the speed apage downloads is very important. After 10seconds, your customer has lost interest inyour page, no matter how interested they

were in the topic. You can't control allaspects of the download - so it's importantto do what you can.

What is EDI?

- Exchange of electronic data between companies using

precisely defined transactions Set of hardware, software, and standards that

accommodate the EDI process

In 1996, theNational Institute of Standards and Technologydefined electronic data interchange as "the computer-
