Google reported a 15% year on year increase in global ad revenue in Q4 2008 to $5.5 billion, despite experiencing its first quarterly profit decline in the same quarter.
Ad revenues from Google’s additional network of websites, specifically through AdSense programs, rose from $1.6 billion to $1.7 billion year on year.
However, the proportion of total revenues generated from UK operations fell from 14% to 12% year on year, though UK revenues still totalled $685 million.
Eric Schmidt, Google’s chief executive, said: “Google performed well in the fourth quarter, despite an increasingly difficult economic environment. Search query growth was strong, revenues were up in most verticals, and we successfully contained costs.
“It’s unclear how long the global downturn will last, but our focus remains on the long term, and we’ll continue to invest in Google’s core search and ads business as well as in strategic growth areas such as display, mobile and enterprise,” he added.
