The 3 largest US search providers continued their long-term dominance of the online search market in May 2010, according to data from The Nielsen Company.
In total, Americans performed 9.25 billion online searches in May 2010.
Just three providers, Google Search, Yahoo Search, and MSN/Windows Live/Bing Search, accounted for slightly more than 90% of all US searches during May 2010, MarketingCharts reports. Google held a 65.1% share of the search market with 6 billion searches, its share flat from the previous month, while Yahoo came in second with 13.8% market share and 1.27 billion searches, enough to boost its share by 0.3 percentage points.
MSN/Windows Live/Bing closely trailed Yahoo with about 2 billion searches and 13% market share (up 0.1 percentage points from April 2010). The fourth-ranked provider, AOL Search, accounted for only about 191.2 million searches and 2.1% market share (down 0.4 percentage points).
Overall, the US search market showed minimal fluctuation between April and May 2010. AOL lost the most percentage points from its April market share figure and Yahoo gained the most. Four of the top 10 providers, including Google, maintained flat market share compared to the prior month.
