Uncertainties lie within the site’s overall usability. The less user-friendly your site is, the more uncertainty visitors will experience while navigating the site. Site usability goes back to the importance of page and business process flow. In the following subsections, we will discuss uncertainties, as well as focus on the importance of the overall navigational structure of the site, which will enhance the user experience.
The bounce-around effect measures how much bounce-around is happening on a given navigational path on your site. It measures how many of your visitors seem disoriented and unable to locate the page they are looking for.
A typical linear navigational path may be home page→category page→product page→checkout (see Figure 6-4). Of course, people do not navigate around your website in a linear fashion (see Figure 6-5). You can, however, expect the majority of visitors to follow general paths if they find the information they are looking for. Users who are impacted by the bounce-around effect find themselves going back and forth between different pages on a site for a better sense of “what to do next” and “where to go from here.”
Call-to-action buttons must be clearly visible as well as easy to use. Requiring users to complete too many steps and to make too many movements throughout a site will result in lower conversions. The inability to locate calls to action is a problem that manifests itself in many different forms. Some sites are so unorganized that you cannot find the company contact information. A friend recently signed up for the Geico.com emergency car service. Unfortunately, within a week of starting the service, her car broke down and she needed to be towed. Luckily, she was close to home and was able to access her computer. She searched for 20 minutes on the Geico website for the emergency roadside number and could not find it.
On ecommerce sites, this problem takes a different shape. Some sites use “Add to Cart” buttons that are too small to notice. Sometimes other buttons are competing with the main call-to-action button. On NewEgg.com (see Figure 6-6), the product page offers a variety of call-to-action buttons. These include “Add to Cart,” “Add to Wish List,” “Email This Page,” “Print This Page,” and “Price Alert,” which are all valid options. However, in cases such as this, the “Add to Cart” button must stand out.
Figure 6-7 shows another example of a call-to-action button that is difficult to find and use. The “Add Selected Products to Cart” button is at the top of the page, and users must enter the quantity of the product they desire and then scroll up to add the product to their cart.
Figure 6-8 shows an example of a site that has a hidden call to action. The call to action is far below the fold and is the same size as other elements. Because of these issues, visitors can miss the call to action completely (it’s at the bottom right and is labeled “Add to Basket”). Remember, the call to action is the most important element of the page, so it must be visible enough to draw users’ attention.
