Mobile is meaningful at Google

The most important number in a Google Inc (NASDAQ:GOOG), (NASDAQ:GOOGL) for a long time has been mobile revenue. Though the company is still the biggest earner in mobile ads, its lead over competitors like Facebook Inc (NASDAQ:FB) is nowhere near the monopolistic position the company has held on desktop for the last number of years. With user eyes drifting from their desktop to their smartphone, investors and analysts are following Google for signs of weakness.

This afternoon’s earnings report certainly didn’t give those betting against Google Inc (NASDAQ:GOOG) what they’re looking for, but the firm’s future on the small screen is far from secure. Google needs to continue to show momentum behind mobile campaigns, such as its enhanced campaign technology, in order to prove its ability to keep control of the market.

Google begins to face competition

The race for mobile is the first time that Google Inc (NASDAQ:GOOG) has really competed for a number of years. The fact that the company produces products like Android and Google Fiber at zero to negative margins implies that its not really competing with the other players in the market. Facebook Inc (NASDAQ:FB) mobile efforts are different, however, and they show that the firm could face challenges in its core business.

Advertising on mobile is where Facebook Inc (NASDAQ:FB) has excelled since going public, and the company’s stock has been rewarded in response to its success in the area. While Mark Zuckerberg’s company increases its share of the mobile advertising market, Google has lost some of its hold on the business. It will not be able to control smartphone ads as it has ads on the desktop, and that may not be the only business that Facebook is looking to take from Google Inc (NASDAQ:GOOG), (NASDAQ:GOOGL).

Today’s numbers showed no weakness in Youtube, which has begun to be regarded as one of the most valuable parts of Google Inc (NASDAQ:GOOG), but companies like Facebook and Yahoo are more and more interested in taking parts of that business away from the search giant. Video share is going to become a big worry for Google going forward, as are any other parts of the business that come under pressure from competitors.
