Yahoo search just dropped from No. 2 to No. 3.
According to a report released today by Nielsen Company, Microsoft’s search services, which include Bing search, overtook Yahoo search in the United States as the No. 2 search engine during the month of August.
Nielsen said that the Microsoft search services had taken 13.9 percent of the search market in the United States compared with Yahoo’s 13.1 percent. Nielsen also noted that neither company came close to Google’s domineering 65 percent share of the United States search market.
The Microsoft search growth coincides with a decrease in usage of Yahoo’s services.
It’s important to note that Bing and Yahoo announced a search deal in 2009 that would use Bing’s search technology to power the Yahoo search engine. Yahoo officially began using the search technology behind Microsoft Bing in August, but the entire transition to the service won’t be completed until 2012.
Nos. 4 and 5 on the list of United States search services are Ask.com, owned by IAC/InterActiveCorp, and AOL. Both account for 2 percent of the search market apiece and have remained stagnant, according to Nielsen’s research.
