Google reported revenue of US$5.54 billion for the quarter, which ended Sept. 30, up 31 percent compared with last year's third quarter.
Deducting the commissions Google pays to its advertising partners, revenue came in at $4.04 billion, slightly below the $4.05 billion consensus expectation from analysts polled by Thomson Reuters.
Net income was $1.35 billion, or $4.24 per share, compared with $1.07 billion, or $3.38 per share, in 2007's third quarter.
On a pro forma basis, which includes one-time items, net income was $1.56 billion, or $4.92 per share, exceeding analysts' consensus expectation of $4.75 per share.
"Google had a good quarter. Traffic and revenue were both solid and we kept tight controls on costs," said Google CEO Eric Schmidt during a conference call.
