The internet company recorded marketing services revenue, which includes advertising, of $911m for the last quarter of the year, up from $545m for the same period last time.
Revenues were $1.08bn for the fourth quarter of 2004, a 62% increase compared with $664m for the same period of 2003. Revenues, excluding traffic acquisition costs, were $785m for the fourth quarter of 2004, a 54% increase compared to $511m for the same period of 2003.
The company also predicted strong growth for the year ahead, saying that it expected revenue to rise by 31% in 2005.
Terry Semel, chairman and chief executive officer of Yahoo!, said: "Yahoo! moved at an impressive pace in the fourth quarter, capping another record year for the company. Our users were more engaged in 2004 than ever before because of Yahoo!'s relentless focus on delivering the most innovative products and services on the internet.
"Yahoo! also benefited from the growing acceptance of online advertising with marketers who recognise its effectiveness and are therefore increasingly using this platform to reach their consumers."
He told reporters that online adspend for the last quarter of 2004 was equal to that spent during the whole of 2002.
