Week 3: Criteria for optimal web design (designing for usability)

In the first week, I have read an article named Criteria for optimal web design (designing for usability)

The web site first shows some questions to address important human factors concerns in the design and building of usable websites. The questions are below:

• How should information be positioned in a typical website?
• What is the best way to arrange menus?
• How can I make my website’s structure more navigable?
• How should text be presented within a website?
• How can I effectively use images on my website?
• Are frames ever appropriate?
• How can I design a visually pleasing interface that follows usability principles?
• How can I reduce the major user annoyances on my site?
• How can I make my site more accessible to children?
• How can I make my site more accessible to older adults?
• How can I make sure my site follows general Web conventions?
• How can my website promote customer sales and loyalty?
• How can I make my site more appealing to international users?

I would use the first question to further explain the design of websites. It describes a study found that a website is in higher usability when the text inside is 1) written concisely 2) easily scannable and 3) written in objective. That means it suggests the text should be:

• Very CLEAR and SHORT
• Include only ONE key concept per paragraph
• Use highlighted keyword or phrases
• Use bulleted lists when possible

The below example shows all the recommendations:

Users have grown accustomed to looking in certain areas on a screen to find specific items (Bernard, 2001). Analyzing users’ expectations of where they expect specific web objects to be located revealed that generally,

• Internal web links were expected to be located on the upper left side of the browser window (Figure 1).
• External web links were expected to be located on the right side or lower left side of the browser window (Figure 2).
• The “back to home" link was expected to be located at the top-left corner and the bottom-center of the browser window (Figure 3).
• The internal search engine was expected to be located at the top-center of the screen (Figure 4), and
• Advertisement banners were expected to be located at the top of the browser window (Figure 5).
• The login/register button was expected to be located at the upper-left corner of a web page (Figure 6).
• The shopping cart (basket) was expected to be located at the top-right corner of a web page (Figure 7).
• The help button was expected to be located at the upper-right side (Figure 8).
• Links to specific merchandise items were expected to be located at the left upper-center of a web page (Figure 9), and
• The account/order button was expected to be located at the upper-right of a web page (Figure 10).
