A New Model to Help Improve Website Usability Offering an optimal blend of text, graphics and white space will keep your visitors clicking.

For centuries, artists and writers have struggled to marry form and function. Click around online for a while and it becomes clear that web designers still grapple with the challenge. Achieving the optimum blend of text, graphics and white space eludes most companies. Too much text is likely to overwhelm, while too little leaves users guessing what the graphics represent. Too much white space wastes valuable real estate, while too little makes users feel cramped and confused.

The optimum blend for any given industry or application varies. According to a June 2010 study published by Oneupweb, a digital marketing agency in Traverse City, Mich., it may require more of one ingredient and less of another to accommodate differences in user behavior (how people tend to interact with a certain genre of sites), online constraints (including two-dimensional screens and browser compatibility) and the nature and depth of the content. E-commerce and higher-education sites, for example, must incorporate more textual content, whereas B2B sites tend to make greater use of graphics and white space.
