CPMs of large websites dropping while CPMs of small websites rise

The PubMatic AdPrice Index tracks eCPMs across 3,000 sites that work with PubMatic ad-network. While I can’t speak to the list of sites that is included, the findings aren’t surprising – large sites (that have over 100 million page views monthly) are dropping in eCPM because social networks have more page views than they know what to do with and are difficult to monetize because performance is so poor. As these sites eat up more of the user time and attention spent on the web, niche content sites that have more engagement and perform significantly better can charge higher premiums. more findings on the PubMatic site, and continual update of data.
