Why Usability Effects The Bottom Line

It is important to understand that the core strategy for most websites can be summarized as a formula, where

Visitors * Conversion Percentage * Order Price = Revenue

This could be translated to sites that are intended to produce leads.

Usability dramatically effects the conversion percentage of a site. Therefore, proper planning and design of the navigation and usage models are important to the bottom line of a website.

Consider the following example:
A designer decides to be “bleeding edge” and put all of the menus for navigation of the web site under a single, unlabled, dot. Visitors come to the site, can’t find anything, and leave. Never make your visitor have to learn how to navigate your website.
