Google, Bing Both Win More Search Market Share

Google Bing Yahoo logosAnother month and another new release of comScore search engine rankings for the U.S. for May 2013. Google and Bing are both up, while the other top search engines comScore tracks (Yahoo, Ask, AOL) were flat or saw declines.

Not surprisingly, Google led the way for search share in May, and grew its search market share to 66.7 percent, up from 66.5 percent in April. Google has the identical search share of 66.7 percent when comparing May 2012 and May 2013.

Bing grew to 17.4 percent in May, up from 17.3 percent in April. This is a significant increase from its 15.4 percent search market share in May 2012.

Meanwhile, Yahoo dropped slightly from 12 percent in April to 11.9 percent in May. Yahoo is down considerably from May 2012, when it had a 13.4 percent search market share.

This continues the trend of Microsoft’s Bing and Yahoo simply swapping search share rather than making inroads on Google’s massive search share.

Ask held steady at 2.7 percent from April to May, but AOL's search market share fell to 1.3 percent, down from 1.5 percent. AOL's search market share has only been this low one other time, when it previously hit this record low in August 2011.

When looking at the 20 billion search queries conducted in May specifically, Google remained static with 13.4 billion, while again Microsoft gained 1 percent to 3.5 billion searches, while Yahoo lost 1 percent to 2.4 billion. Interestingly, AOL lost 8 percent of search queries over the previous month.
