Total sales for the third quarter ended Sept. 30 amounted to US$3.2 billion, up 59 percent from the same period last year, and beating consensus analyst expectations of $3.12 billion, as polled by Thomson Reuters.
Roughly two-thirds of sales, or 66 percent, came from ads placed on mobile devices, Facebook reported, up from just under half of all revenue coming from mobile a year ago.
Facebook's ability to monetize its site with ads on smaller screens was in previous years a concern to investors, but the company has demonstrated considerable progress there.
Facebook also reported decent gains in growing its user base, a critical element in attracting and retaining advertisers. The number of users who logged in at least once a month clocked in at 1.35 billion, Facebook said, up 14 percent.
Meanwhile, the number of users who logged in daily -- another important metric -- rose by 19 percent to 864 million.
Facebook stock was at around $79.99 in after hours trading following its earnings report, down slightly from its close of $80.77, possibly signaling lingering investor concerns over Facebook's progress toward growing its audience.
Facebook nearly doubled its net income for the third quarter, to $806 million.
The company's adjusted earnings per share was $0.43, above analyst estimates of $0.40.
CEO Mark Zuckerberg, in Facebook's announcement, called the results "strong," showing a "good quarter."
