RESTON, VA, October 10, 2007 – Comscore, Inc.

The study found that more than 750 million people age 15 and older – or 95 percent of the worldwide Internet audience – conducted 61 billion searches worldwide in August, an average of more than 80 searches per searcher.

Search Activity across Worldwide Regions

The Asia-Pacific region, which includes large markets such as China, Japan and India, saw 258 million unique searchers conduct 20.3 billion searches. Europe reported the second-most searchers (210 million) and searches (18 billion), followed by North America, with 206 million searchers and 16 billion searches. The Latin American region demonstrated the heaviest search activity per person, with more than 95 searches per searcher in August.
