Google's second-quarter results show a 6% drop in cost-per-click compared with the year before as consumers and advertisers continue to shift their focus to mobile, where ad inventory is cheaper. "The revenue opportunity is very, very high, but right now mobile does not monetize as well as other forms," said Google Chief Business Officer Nikesh Arora, who is leaving the company for a job at SoftBank. Arora will be replaced by Omid Kordestani, an adviser to CEO Larry Page, for the time being.
