Google got a belated gift from the holiday-shopping season. Excluding certain items, Google reported a profit of $ 10.65 a share, exceeding analysts’ estimates.(19)Revenue was $ 11.34 billion, up from $ 8.13 billion in the same period a year ago. For its fiscal year, Google hit $ 50 billion for the first time. The financial surge sent Google shares up nearly 5% in after-hours trading, to $736. 40, on Tuesday. Still, Google’s results were tempered by an unnerving trend: The price advertisers pay Google each time someone clicks on an ad dipped 6% from the year-ago quarter—the fifth-straight quarter that so-called cost-per-click prices have declined, year over year. Results on the heels of a third quarter in which earnings tumbled, gave investors a better sense of how the growing popularity of smartphones and tablet computers are affecting prices in the digital-advertising market. Like Facebook, Zynga and others, Google faces a vexing issue:(20)As millions of people give up conventional PCs for mobile devices, advertisers pay Google lower rates for search ads on smartphones and tablet computers than they do for ads found through searches on desktop PCs and laptops. So far, advertisers haven’t been willing to pay as much because of the disparity in screen sizes. But Google’s fourth-quarter numbers offered hope. The company’s advertising rates fell less than in previous periods.(21)Google’s earnings have risen overall, because the total number of clicks on the ads—for which Google is often paid—have steadily climbed.
