Viewability data extensions
Unified Auction provides specific viewability metrics within the bid request. Through select viewability partnerships (MOAT Analytics), Unity can pass historical viewability measurements based on the Media Rating Council (MRC) and GroupM definition within each bid request.
Viewability standard definition
The MRC viewability requirement states that at least 50% of a video ad must be in view on-screen for 2 seconds before it counts as viewable.
metrics object
Based on OpenRTB specification 2.5 section 3.2.5, Unity sends viewability data through the metrics
