In its third-quarter conference call, Google said people who are accessing its products and services through their mobile phones are now adding the equivalent of 1 billion US dollars a year to the company's revenue.
Google also said that its mobile search queries have grown fivefold over the past "couple of years", but it acknowledged that the cost per click it can charge for advertising on mobile phones is a "good bit lower" than on PCs because people are less likely to complete a transaction.
Google added that it is "monetising" over two billion YouTube views each week, up 50% year-on-year, but declined to say whether YouTube is yet profitable. The search giant also said that total YouTube views average two billion a day.
Eric Schmidt, Google's CEO, said on the call that the success of Android, Google's smartphone operating system, has been well past what he "had ever hoped for." He added that people who use Android search twice as much as other mobile phone users. source: recording of Google earnings call
