eWeek: At the Search Engine Strategies show, Bing exec Yusuf Mehdi explained that Microsoft trailed behind Google for so long because his company focused only on providing good results for the most popular queries.
"We missed the boat early on that the focus was about the long tail. We actually focused a lot on the head of the queries," he said. "It turned out the long tail was much more important."
Currently Google enjoys 65 percent of the U.S. market share, while Microsoft Bing has just 11.5 percent of searches.
