AWS Elemental MediaTailor now offers Yield Optimization, a new capability that automatically monetizes unused ad inventory with Amazon Ads demand during server-side ad insertion (SSAI) for livestreams. Available exclusively to publishers in the Amazon Publisher Services (APS) Streaming TV program, yield optimization turns unfilled ad breaks into monetized impressions at zero cost to enable and with no additional infrastructure required. Because ads are stitched directly into the stream before reaching the viewer, they play seamlessly on every device.
