“According to an infographic from Microsoft Tag, 51% of smartphone users are more likely to buy from a retailer with a mobile specific application or web site, however: only 4.8% of retailers have a mobile presence.
A recent study by Google, “The Mobile Movement: Understanding Smartphone Users” reports 77% of smartphone users visit search engine websites followed by social networks. And nine out of ten smartphone searches results in an action (purchasing, visiting a business, etc.). Mobile use is growing faster than all of Google’s internal predictions, with YouTube seeing 200 million mobile playbacks a day,according to Eric Schmidt.”
