Bing’s U.S. search market share was 6.47% in July, per web analytics service StatCounter. Bing’s market share peaked at 6.61% in March. The highest Bing’s global search market share has been this year was in January, at 3.03%, a month before new Bing was announced. This claim seems a bit odd, considering around this time 10 years ago, Bing’s search market share was 17.9%, per comScore.
