According to ReadWriteWeb:
U.S. advertisers spend nearly $40 billion a year for online advertisements, but 31% of their ads are never seen. That means $12.4 billion will be wasted on U.S. online ads this year. That’s the average across all sites; on some sites, only 7% of the ads were “in-view,” meaning 93% of them went unseen.
On average, 4% of ads were delivered to viewers outside the desired geography, with some campaigns running as high as 15%. That means some ads were shown to customers in places where the product is not sold.
