Google saw its revenues increase 17% between October and December, as its advertising earnings rose strongly.
However, its shares fell 5% in after-hours trading, as the results came in at the lower end of market targets.
The US search engine giant enjoyed revenues of $6.67bn (£4bn) during the quarter, up from $5.7bn a year earlier.
Its net profit also shot up to $1.97bn, but a comparison with a year earlier is difficult because of a one-off charge in the last three months of 2008.
A year earlier Google’s profit was only $382m, due to it having to write down $1bn to cover a fall in the value of its investments in internet group AOL and wireless service provider Clearwire.
“Given that the global economy is still in the early days of recovery, this was an extraordinary end to the year,” said Google chief executive Eric Schmidt.
Google’s net profit for 2009 as a whole rose 54% to $6.52bn.
