The optimism many publishers felt about their programmatic advertising prospects last month may have been well placed.
With more advertisers returning to the market, both for open exchange investment and private marketplace deals, and active advertisers continuing to increase their spending from spring lows, CPMs continue to rise in open exchanges.
The revenue data management service Staq found that display CPMs across open exchanges in the U.S. spent most of August increasing, hitting a high of $1.35 on August 23, up from $1.16 August 1. Those figures draw on revenue data from 50 publishers of different sizes, who generate more than $1.2 billion in combined annual revenue.
