In addition to Compete's report, we have comScore's December qSearch analysis of U.S. search market share.
Google grew its lead slightly to 47.3 percent, up 0.4 percentage points over November. Yahoo gained three points to 28.5 percent market share. Microsoft sites (including MSN Search and Live Search) dipped by 0.5 points to 10.5 percent share; Ask.com and related IAC sites, like Excite and MyWay, lost 0.1 point to keep fourth place with 5.4 percent share; and AOL and the Time Warner network remain in fifth place with 4.9 percent market share, down 0.2 points in December.
All the engines basically continue on the same trends -- Google slightly up, Microsoft slightly down, and Yahoo, Ask and AOL fairly flat. The trends are especially apparent if you look with a long view, as Danny did at Search Engine Land.
