Advertising Age reports: “Cost-per-thousand ad impressions for online publishers are generally off about 20%, according to several people on both the buying and selling side, and sell-through rates are dropping. And where publishers used to unload 60% of their inventory, some are now able to sell only 30%.”
But perhaps indicating more trouble ahead is just how cheap the low end of the market has gotten. An August study from the Interactive Advertising Bureau and Bain Capital found the average CPMs on ad networks ranged from 60 cents to $1.10, only 6% to 11% of the prices publishers could command when they sold inventory directly. And the pricing for networks appears to be getting worse not better. CPMs for ad-network-sold ads are dropping, some by 50% year-over-year, according to a recent study of pricing by Pubmatic, which tracks pricing among many Long Tail ad networks.
