David Wehner, Facebook's chief financial officer, pointed to Asia-Pacific, especially India, as one of the most promising areas for continued user growth.
Asia-Pacific "has been a consistently good performer for us over the last several quarters and we will continue to invest our global sales resources to drive opportunities there", Wehner said in an interview with Reuters.
Facebook is one of the biggest beneficiaries as advertisers move money away from television to the internet and mobile platforms. The company has been beefing up its presence in the mobile video market, where Snapchat and YouTube pose strong competition.
The company is also courting advertisers to experiment with Facebook Live, its recently launched live video feature.
Facebook still has several untapped areas for revenue opportunities, including its WhatsApp and Messenger apps, both of which have more than 1 billion users.
But Wehner said the company does not plan to monetise them any time soon, and that it is instead focused on building interactions between businesses and users on the apps.
Facebook also owns picture-sharing app Instagram, which recently announced it has more than 500 million users.
Facebook has yet to say how much money Instagram makes, but research firm eMarketer predicts it will make US$1.5 billion in revenue this year.
Excluding items, Facebook earned 97 US cents per share for the second quarter ended June 30. Analysts on average had expected a profit of 82 US cents per share, according to Thomson Reuters I/B/E/S.
Net income attributable to Facebook's stockholders rose to US$2.05 billion, or 71 US cents per share, compared with US$715 million, or 25 US cents per share, a year earlier.
Total revenue rose 59.2 per cent to US$6.44 billion, ahead of analysts' average estimate of US$6.02 billion.
