“Search engine marketing firm Efficient Frontier has upped its estimates for search ad spending this year. The company now expects spending to increase between 15 and 20 percent, up from its earlier estimates of 10 to 15 percent growth, in part due to the economic recovery. By contrast, Efficient Frontier says search ad spending increased six percent in 2009.”

In Q4 2009 Google added to its enormous market-share lead:

“That was a shift from previous reports, which had indicated that Google was losing ground to Bing. Efficient Frontier says Google’s share of overall search ad spending increased to 74.5 percent from 73.9 percent during the previous quarter. Bing’s share, meanwhile, shrunk to 5.1 percent from 5.3 percent.”
