Microsoft’s New Search at Bing.com Helps People Make Better Decisions
The explosive growth of online content has continued unabated, and Bing was developed as a tool to help people more easily navigate through the information overload that has come to characterize many of today’s search experiences. Results from a custom comScore Inc. study across core search engines show that as many as 30 percent of searches are abandoned without a satisfactory result. The data also showed that approximately two-thirds of the remaining searches required a refinement or requery on the search results page.
