comScore has put out its monthly search engine rankings for the United States, looking at the month of November. Google sites made up 67% of explicit core search queries conducted, up 0.1% from October, according to the firm. Explicit core search excludes contextually driven searches that don’t reflect specific user intent to interact with search results.

Microsoft sites were up 0.2% at 16.2% of queries, and Yahoo sites were down 0.1% at 12.1%. Ask Network was behind Yahoo with 3% of queries (down 0.2%), and AOL followed with 1.7% (down 0.1%).

There were about 17 billion explicit core searches performed in November, according to comScore. Google sites accounted for 11.4 billion of them. Microsoft sites accounted for 2.7 billion searches, and Yahoo accounted for 2.1 billion. Ask had 506 million, and AOL had 297 million. Again, this is just the U.S.

Of course, Yahoo is actually powered by Microsoft’s Bing. comScore says that in November, 69.4% of searches carried organic search results from Google, while 25.4% of searches were powered by Bing (up 0.4 percentage points).
