Here is the browser market share for March 2013, based on traffic to my top site (number in parentheses shows change from February 2013):
Google Chrome: 38.84% (+1.42%)
IE: 29.57% (-0.82%)
Firefox: 25.02% (-0.93%)
Safari: 3.66% (+0.16%)
Opera: 1.12% (+0.01%)
Google Chrome was strong in March, gaining 1.42% to 38.84%. Google’s gain came at the expense of both IE and Firefox, both lost more than 0.8% during March. StatCounter reported a similar trend, though the changes (both increases and decreases) it reported were not as dramatic as what we saw.
There were reports circulating that IE 10 has gained market share since its release on Windows 7. We saw a similar trend, with IE 10′s share of all IE browsers climbing from 3.76% in February to 6.22% in March. IE 8 remains as the dominant IE browser at 50.1%, followed by IE 9 (34.2%) and IE 7 (8.1%).
