Google Continues Search Dominance

It appears Google's competitors in Internet search have an uphill climb. New research shows how the company is putting even more distance between itself and its rivals.

Efficient Frontier, a search-marketing tech provider, examined more than 17 billion impressions and 270 million clicks on search ads running through its system during the fourth quarter of 2007 and the same period a year earlier.

The results show the yawning gap Google has opened with its rivals, Microsoft and Yahoo!, because it continues to attract a growing majority of Internet searches.
