Executive Summary
This report distills the data from our major international usability study into the essence of e-commerce, discussing the strategic implications of our findings for the future of e-commerce. This is the report to give to your boss if he or she doesn't have time to read the detailed reports.

Category Pages
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. 28 design guidelines.

Product Pages
Users need sufficient information about a product before purchasing it online. Product pages provide that information using a combination of text and images. Effective product pages show availability, product options, and total cost. Good images also matter. 30 design guidelines.

Shopping Carts, Checkout & Registration
Filling out forms correctly during shopping is very difficult for most users. Forcing people to register during their first purchase is a confusing and frustrating tactic that drives customers away. Better designs mean more customers can complete the shopping process. 32 design guidelines.

Search
Many of our users went right to the site's search tool (unless it was hidden) but there were several reasons search didn't always help them. How to improve search results and search pages in product catalogs. 29 design guidelines.

Selling Strategies
Some sites drive their customers away with high prices, unreasonable shipping costs, or unavailable items. Sites that learn to avoid these problems can then focus on tactics for achieving additional sales through cross-selling, recommendations, and gift-giving. 47 design guidelines.

Trust and Credibility
