Here’s Compete’s relative ranking of the top search engines for December 2006.
And here’s comScore’s December 2006 US market share data (6.7 billion total searches).
The two sites disagree on Yahoo! and AOL directionally. For Yahoo! comScore shows a gain; Compete shows a loss of share. Regarding AOL, Compete shows a bit of a recovery while comScore shows further erosion.
To throw in a bit of local search perspective: the local products of the majors are capturing about 1% of the traffic of general search. comScore says local search is 13% of all search but it’s a much bigger number when you consider (per WebVisible-Nielsen research) that as much as 51% of local search queries don’t carry a geographic modifier.
