ComScore's monthly comScore qSearch analysis of the U.S. search marketplace indicates that in July 2008, U.S. users conducted 11.8 billion core searches (up 2% vs. June) as Google Sites slightly
extended its lead in core search market share by 0.4 percentage points.
Google Sites led the U.S. core search market in July with 61.9% of the searches conducted--up from 61.5% in
June, followed by Yahoo Sites (20.5%), Microsoft Sites (8.9%), Ask Network (4.5%), and AOL LLC (4.2%).
The stats are based on the five major search engines including partner searches and
cross-channel searches. Searches for mapping, local directory, and user-generated video sites that are not on the core domain of the five search engines are not included in the core search
numbers.--Tanya Irwin
