Google reported a 27% increase in revenues for the last three months of 2011, but even that was not good enough to meet Wall Street estimates, sending the shares tumbling.
Google shares fell 10% in after-hours trading to $575.
It reported 3-month revenues of $10.6bn (£6.8bn). Its net profit rose 6.4% to $2.7bn.
“Google had a really strong quarter ending a great year,” said chief executive Larry Page.
