Market researcher Statcounter says Google’s share of U.S. search traffic, excluding mobile devices, declined to 75.3% in December from 77.5% in November, after Mozilla, the maker of the Firefox browser made Yahoo the default search engine. Yahoo’s share of search traffic excluding mobile devices grew to 10%, from 8%.
Google’s Chrome and Microsoft’s Internet Explorer are the top browsers on personal computers, with average U.S. market shares of 37% and 34%, respectively, in 2014. Chrome’s share has quadrupled since 2010, helping Google to be less dependent on other browsers for search traffic.
Google faces potentially larger losses on mobile devices. There are reports that Apple is considering dropping Google as the default search provider on its Safari browser, which is standard on the iPhone and iPad. Statcounter estimates that 54% of U.S. mobile traffic came from Safari in December, compared with 41% from Google browsers including Chrome.
