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 object in the bid request.

Attribute	Data Type	Example	Description
type	string	valid_and_viewable_perc	The specific metric measured by viewability partner (in this case, the MOAT Valid and Viewable Rate, defined as the number of valid impressions that were viewable under the MRC standard).
value	float	0.995	Value of the metric in numeric format (precision-3).
vendor	string	MOAT	Viewabilty measurement partner.
