Accounts for 10.5 per cent of all web traffic at end of February 2012.
Research from ad firm Chitika shows mobile data traffic accounted for over a tenth of all web traffic in the last week of February, which is up 34.4 per cent from July 2011.
Chitika blogged: "On February 17th, Chitika Insights reported a ten per cent decline in Windows web browser market share as seen on our network, which we believe could be related to the trend of consumers who prefer to do more of their browsing from a mobile or tablet device."
Additionally, the results show that web usage peaks at different times in the day for PC and mobile platforms.
Mobile web traffic dips significantly overnight, rising in the US during the morning hours and spiking at between 8-10pm with highs of 18.3 per cent. Meanwhile, PC web usage peaks in the early hours of the morning with highs of nearly 95 per cent of all web traffic.
The firm continued, saying: "For publishers and advertisers, this data can be extremely valuable in fine tuning advertising strategies to match traffic composition and the time of day in order to optimise their revenues."
