From the Nielsen Company:
Top Ten Search Providers March 2010
Searches represent the total number of queries conducted at the provider. Example: An estimated 6.4 billion search queries were conducted at Google Search, representing 65.7 percent of all search queries conducted during the given time period.
Note: MegaView Search data – including total searches, unique searchers, search share, and all other search figures – cannot be trended with search results prior to October 2009 due to recent methodology changes.
