“Many of the leading ad networks can now reach more than half of the online population in Germany, demonstrating their ability to deliver on aggressive campaign reach objectives,” said Mike Read, SVP and managing director, Comscore Europe. “But they are also helping improve the efficient allocation of ad campaigns to publisher sites through demographic and content-specific targeting. As this burgeoning industry evolves, increased site content transparency will be essential for continued growth.”
