One of the key take-aways from this is that 55% of sales (whether online, in store or on the phone) happen within an hour of a mobile search occurring. Google, naturally, will use that statistic to justify investment in super-targeted mobile advertising.
The research also reveals that mobile searches are most often done at home or work in the afternoon and evening, mainly because it's "more convenient than firing up the home computer". I wonder if, in the future, we will even identify our personal devices as mobiles as all the capabilities of tablets and smart-phones morph into one, compact super-computer.
The full study is below and well worth a read.
