14 DAY TRIAL // Google gained even more market share in the US in October after the introduction of Google Instant. While the increase is minimal, Google already dominates the space. Google accounted for 66.3 of explicit core searches in the US in the last month according to comScore.
"Google Sites led the explicit core search market in October with 66.3 percent of searches conducted, an increase of 0.2 share points from September 2010," comScore said.
"Google Sites led the U.S. explicit core search market in October with 66.3 percent market share, followed by Yahoo! Sites with 16.5 percent and Microsoft sites with 11.5 percent. Ask Network captured 3.6 percent of explicit core searches, followed by AOL LLC Network with 2.1 percent," the report added.
The overall trends have been stable in the previous month. Google gained a bit of market share but too little to make a difference at its scale.
Yahoo continued to slid down losing 0.2 market share points. Microsoft's Bing on the other hand gained 0.3 points. The other two players in the top five both lost market share, Ask 0.1 percent and AOL 0.2 percent.
More interesting, comScore is now also reporting "powered by" market share data. With Google and Bing behind most searches in the US, these numbers provide a more accurate view of the landscape.
Google accounted for 69.2 percent of organic search results in October, when accounting for AOL which is powered by Google. Bing accounted for 23.5 percent of searches, consisting of Bing and Yahoo Search combined.
Ask, the only independent search engine left, recently announced that it will be giving up its efforts of running a crawling and indexing engine and will most likely be relying on Google for the results in the future.
