Google has reported a quarterly profit rise of 32% to $2.17 billion (£1.4 billion) for the three months to September 30.
The figures, up from $1.6 billion for the same period last year, were helped by higher advertising revenues and the success of the Android mobile phone operating system .
Overall revenues were up 23% to $7.29 billion.
Google said 16% more users clicked on adverts on its website during the quarter than a year earlier. It is also charging companies more to list their adverts.
Google chief executive Eric Schmidt said: “Our core business grew very well, and our newer businesses – particularly display and mobile – continued to show significant momentum.
“Going forward, we remain committed to aggressive investment in both our people and our products as we pursue an innovation agenda.”
