Zemanta offers Zemanta One, the world's first multi-channel demand-side platform built for performance. Traditional programmatic advertising platforms are built to serve impressions but Zemanta has pioneered the technology that empowers trading desks to show actual return on ad spend. Zemanta helps advertisers break free from reach and frequency metrics by determining which placements and creatives lead to the right users engaging with their ads and websites. This unique approach offers advertisers the opportunity to capture true consumer engagement, deliver wanted outcomes, and return on ad spend.
