The percentage of website traffic coming from mobile devices jumped from 17.5% in Q3 2012 to 23.1% in Q4 2012, according to a new report from Walker Sands. That 23.1% share represents an 84% hike from 12.6% in Q4 2011, and is based on an examination of web analytics data across a range of Walker Sands’ B2B and B2C clients across multiple industries. The rate of growth outpaces smartphone adoption growth over that time frame, suggesting that consumers are spending more time accessing the internet from their mobile phones. That trend doesn’t appear to be easing, either. Results from a Prosper Mobile Insights survey released this month showed that 34.7% of American smartphone and tablet owners surveyed said they would spend more time this year with their devices, compared to just 5.7% who said they would spend less. Although a plurality of mobile time is spent texting, connected activities such as social networking and browser access account for more than 10% of mobile time, according to Nielsen.
