Summary Category pages organize and prioritize a site's offerings.
Home pages are one type of category page.
Some home pages clearly show what the site sells, but others confuse users by obscuring the purpose of the site. Product listing pages can be tricky to design because they must provide the right amount of information, and organize it well. The findings in the report are based on usability testing of 20 ecommerce sites with 64 users. Richly illustrated with color screenshots from many different websites, showing usability problems we found in our testing as well as examples of highly-usable category pages. This document is a part of Nielsen Norman Group's series of design guidelines for e-commerce user experience .
