Use of ad networks increased form 5% of total ad impressions sold in 2006 to 30 percent in 2007, according to the “Digital Pricing Benchmarking Study” from Bain & Company. Yet as online publishers see growth rates of 20-30 percent in ad revenue, the advertising opportunities leaves publishers with excess inventory that they sell to ad networks at up to 90 percent discounts versus direct sales rates, Bain said.
