In the aftermath of Bing and Yahoo integrating their search ad platforms, the "early winner" seems to be Google, whose share of paid search spending rose more than two percent between the second and third quarters of this year. That's one of the conclusions in the latest quarterly report from Efficient Frontier, a search marketing agency that manages more than $900 million in annual digital spending.

The company says that Google's share of paid search spending rose from 75.8% in Q2 2010 to 77.9% in Q3 2010. Paid clicks at Google are also up 9% year-over-year, cost-per-click is up 14% year-over-year, and impressions are up 6% year-over-year, according to the report.
