“Our goal for this study was to gather users’ general impressions of the Google and Bing search engines, including overall functionality, presentation of content, and overall fit with user expectations and needs. We also wanted to see how much attention users paid to advertising space on the two sites.”
(from the report)
“Most users preferred the Bing visual design and thought that it was slightly better in terms of organization and refinement options.”
Overall reasons for preferring Google
• Familiarity
• Enhancements in Bing not enough to convert
• Already using other Google apps
